http://www.telerik.com/community/forums/winforms/editors.aspx\\
Video: http://www.telerik.com/videos/winforms/getting-started-with-radautocompletebox-for-winforms

RadAutoCompleteBox allows the end-user to easily fill-in text thanks to auto-complete functionality and tokens of text. This behavior is similar to the "To" field of Outlook and Facebook where you are filling-in the recipients to which you are going to send a message.

==== * RadBrowseEditor – rbe ====

[[https://docs.telerik.com/devtools/winforms/controls/editors/browseeditor/overview]]\\  [[http://www.telerik.com/community/forums/winforms/editors.aspx]]

Browse to specify a file or folder on disk.

<color red>### Take a look at this control set instead. [[https://docs.telerik.com/devtools/winforms/controls/file-dialogs/overview|File Dialogs]], It looks like this maybe replaces the RadBrowseEditor? ###</color>

//It opens a FileOpen, File Save or Folder Selection dialog apparently without calling the Windows API.//

RadBrowseEditor is a themable control which allows users to select a file or a directory from the file system or directly type the full path to it in the editor.

{{tdn:image84.png?320x29}}

  * ‘DialogType’ – one of a [[http://docs.telerik.com/devtools/winforms/editors/browseeditor/dialog-types|predefined set of dialog types]] determined by the BrowseEditorDialogType enumeration.
    * FolderBrowseDialogradBrowseEditor1.DialogType = BrowseEditorDialogType.FolderBrowseDialog;
    * FontDialog\\ radBrowseEditor1.DialogType = BrowseEditorDialogType.FontDialog;
    * OpenFileDialog\\ radBrowseEditor1.DialogType = BrowseEditorDialogType.OpenFileDialog;
    * SaveFileDialog\\ radBrowseEditor1.DialogType = BrowseEditorDialogType.SaveFileDialog;

### Add the [[https://docs.telerik.com/devtools/winforms/controls/file-dialogs/dialog-controls/radopenfolderdialog|RadOpenFolderDialog]] to this list. I like it much better than the old FolderBrowseDialog. Also see it here, under the RadBrowseEditor. I’m not sure which of those 2 controls are the one to use now.

==== RadCalculatorDropDown – rcdd ====

[[http://docs.telerik.com/devtools/winforms/editors/calculatordropdown/calculatordropdown]]

RadCalculatorDropDown has a simple easy-to-use interface enabling the end user to perform all basic calculations such as addition, subtraction, multiplication, division as well as some more complicated ones – reciprocal, square root, negate.

{{tdn:image88.png?205x229|A screenshot of a calculator Description automatically generated}}


==== RadColorBox – rcb  ====

http://www.telerik.com/help/winforms/editors-color-box-overview.html\\
http://www.telerik.com/community/forums/winforms/editors.aspx

The main purpose of the control is to allow the user to select a color from a color dialog with preset colors or to type the color directly into the text field. The control then displays the color name if it is a named color or the RGB values of the selected color. A small rectangle filled with the selected color is displayed as well.

{{tdn:image89.png?177x37}}

==== * RadDateTimePicker – rdtp  ====

http://www.telerik.com/help/winforms/editors-datetimepicker-overview.html

VIDEO: [[http://tv.telerik.com/watch/winforms/getting-started-with-radtimepicker-for-winforms|Getting Started Video]]

RadDateTimePicker allows interactive selection of dates using a drop down calendar.

{{tdn:image90.png?194x199|A calendar with green and white text Description automatically generated}}

Choose a date (optionally a time of day?)

  * 'Format' = Short (9/24/2012), Long (Monday September 24, 2012), Time (1:24:38 AM), Custom (9/24/2012 1:24 AM)
  * 'Value' - date selected from the picker set in code or via the drop down calendar in the Properties window.<code csharp>this.rdtpStartDate.Value = DateTime.Today;  // Set Start date to today
this.radDateTimePicker1.Value = DateTime.Today.AddDays(1);  // Set the date to tomorrow
this.radDateTimePicker1.Value = DateTime.Today.AddDays(-1);  // Set the date to yesterday</code>

  * By default a single arrow click moves one month and a double arrow click moves three months (called Fast Navigation).<code csharp>rrdtpNameOfControl.DateTimePickerElement.Calendar.FastNavigationStep = 12; // override fast navigation to 12 months so double arrow click jumps 1 year</code>
  * 'MinDate'/'MaxDate' - first and last dates that can be selected in the picker. Attempts to select outside these bounds are ignored.<code csharp>this.radDateTimePicker1.MinDate = DateTime.Today.AddDays(-DateTime.Today.Day);  // set the MinDate to be the first day of the current month.</code>

  * 'NullText’ - text displayed when the NullableValue property is set to null and RadDateTimePicker is not in focus. By default, NullText is an empty string.<code csharp>this.radDateTimePicker1.NullText = "No date selected";</code>

  * 'Format' - The DateTimePickerFormat enumeration values are Long, Short, Time and Custom. Set Format to Custom to enable the CustomFormat property.
  * 'CustomFormat' - format string determines the display of the date in the picker edit. See the Internationalization and Date Formats topic for more information.
  * 'Culture determines the language that the drop down calendar and edit will display in. See the Internationalization and Date Formats topic for more information.
  * 'CalendarSize' - gets/sets the size of the RadCalendar in the RadDateTimePicker drop-down.
  * 'NullableValue' - same as the Value property, but the NullableValue property is of type Nullable DateTime. It can be null – in this case if RadDateTimePicker is not selected it will show its NullText. In case RadDateTimePicker is selected, it will show the last entered date – this allows the end-user to enter and edit the date.<code csharp>this.radDateTimePicker1.NullableValue = null;</code>

==== * RadMaskedEditBox – rmeb ====

[[http://www.telerik.com/help/winforms/editors-maskededitbox-overview.html]]\\  [[http://www.telerik.com/community/forums/winforms/editors.aspx]]

RadMaskedEditBox is a themeable text box that formats and constrains text to a predefined pattern or a pattern you define. RadMaskedEditBox also handles globalization for date and time edits. Date and Time masks allow the user to navigate using the up and down arrow keys.

{{tdn:image91.png?416x262|A screenshot of a computer Description automatically generated}}

The MaskType property defines what type of mask would be used in the masked box:

  * **None**
  * **[[http://www.telerik.com/help/winforms/editors-maskededitbox-date-and-time-masks.html|DateTime]] -** set the **MaskType** property to **DateTime** and the **Mask** property to "d". //See [[http://www.telerik.com/help/winforms/editors-maskededitbox-date-and-time-masks.html|Date and Time Masks]] for more information on how this mask is constructed.//
  * **[[http://www.telerik.com/help/winforms/editors-maskededitbox-numeric-masks.html|Numeric]] -** [[http://www.telerik.com/help/winforms/editors-maskededitbox-numeric-masks.html|The numeric mask]] is used when you need to display these ([[https://msdn.microsoft.com/en-us/library/dwhawy9k.aspx|defined on MS site]]):
    * Percent values.
    * Decimal values.
    * Currency (culture-aware).
    * Fixed point values.
  * **[[http://www.telerik.com/help/winforms/editors-maskededitbox-standart-masks.html|Standard]] -** set the **MaskType** property to **Standard** and the **Mask** property to "(###) ###-###". //See// [[http://www.telerik.com/help/winforms/editors-maskededitbox-standart-masks.html|Standard Masks]] //for more information on how this mask is constructed.//
  * **Regex** - You can define [[http://msdn.microsoft.com/en-us/library/2k3te2cs(v=vs.80).aspx|Regex expressions]] as masks. For example mask **[A-z]** will check for at least one symbol in this range (A-z) in MaskEditBox’s Text.
  * **IP** - allow user to input only **3** digits in **0-255** range in **four** groups
  * **Email** - validate user input for the valid mail. If this email is not valid will notify user with validation icon:
  * ‘TextMaskFormat ‘ - you may want to get a RadMaskedEditBox.Value that differs from what the end-user sees in the editor, or, in other words, from what the Text property provides. In such cases the you will find the TextMaskFormat property useful. It allows you to get variations of of the Text property value taking into account whether you want to get the prompt characters, and the literals used in the mask. The type of the TextMaskFormat property is the MaskFormat enum which provides the following values:
    * ‘IncludePromptAndLiterals’ (default value) - The Value property returns Return the text input by the user as well as any literal characters defined in the mask and any instances of the prompt character.
    * ‘ExcludePromptAndLiterals’ - The Value property returns only the text input by the user.
    * ‘IncludePrompt’ - The Value property returns the text input by the user as well as any instances of the prompt character.
    * ‘IncludeLiterals’ - The Value property returns the text input by the user as well as any literal characters defined in the mask.


==== * RadPropertyGrid – rpg  ====

using Telerik.WinControls.UI; %%//%% required for ‘PropertyGridElement’

rpgControlProperties.SelectedObject = commandBarButton1; %%//%% Show the properties of a RadCommandBar button

  * ‘SelectedObject’ - points to the object whose properties should be displayed
  * ‘HelpVisible’ - show/hide the help section at the bottom which displays the Description attribute of the selected property
  * ‘HelpBarHeight’ – in pixels of the help section at the bottom
  * ‘ToolBarVisible’ shows the toolbar where you would add RadButtonElements for sort by category vs. alphabetical for example
  * ‘’Category’ attribute of the SelectedObject property allows you to create groups in the PropertyGrid (for sort by category vs. alphabetical)
  * ‘PropertySort’ sets default sorting to one of the enumerated values:
    * ‘Alphabetical’ – sorts the properties according to the SortOrder setting (Ascending or Descending)
    * ‘Categorized’ – groups the properties according to their Category attribute
    * ‘CategorizedAlphabetical’ – groups the properties according to their Category attiribute and sorts them Alphabetically, according to the SortOrder setting (Ascending or Descending)
    * ‘None’ – removes sorting and grouping
  * ‘SortOrder’ - Ascending, Descending and None
  * ‘ItemHeight’ - sets the visible items height.
  * ‘ItemSpacing’ - sets the spacing between the items.
  * ‘ItemIndent’ - sets the indent space in the beginning of the items.

The elements of the SelectedObject

Here’s some articles on using the RadPropertyGrid:

  * [[http://www.telerik.com/help/winforms/propertygrid-editors-using-custom-editor.html|Using Custom Editors]] (Replace a spin editor with a track bar editor)

=== Force a RadPropertyGrid to update ===

<code csharp>radPropertyGrid.PropertyGridElement.PropertyTableElement.Update(PropertyGridTableElement.UpdateActions.Reset);</code>

=== ToolTips on Value Column ===

Use the RadPropertyGrid.ToolTipTextNeeded event to specify the ToolTipText for the value column and set the ToolTip.AutoPopDelay.
<code csharp>
private void radPropertyGrid1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
  PropertyGridItemElement itemElement = sender as PropertyGridItemElement;
  if (itemElement!=null)
  {
    e.ToolTipText = itemElement.ValueElement.Text; 
    e.ToolTip.AutoPopDelay = 1000;

RadCheckBox is designed to provide an interface element that can represent an On or Off state using a check mark.

RadCheckBox supports three states. This is controlled by the IsThreeState property. If it is set to false, the ToggleState property, which determines the current state of the check mark, can be On or Off . Otherwise, it can be set to On , Off , or Indeterminate .

CheckBox that observes Telerik Theme settings

  * 'text' text label
  * 'CheckAlignment' checkbox location in relation to the label
  * 'Checked' True/False (get & set) (somehow tied to 'ToggleState' as well)
  * ‘RightToLeft’ = Yes puts the text label to the left of the checkbox.

//RadSplitButton looks the same, and works nearly the same, as RadDropDownButton, but RadSplitButton has a DefaultItem property to specify the item whose Click event should be triggered when the button is clicked. The functionality of RadSplitButton is "split" between the button itself and the dropdown menu//.

  * ‘Items’ – the possible button contents: RadMenuItem, RadMenuSeparatorItem, RadMenucomboItem, RadMenuButtonItem, RadMenuHeaderItem
  * ‘Image’ - property of the RadMenuItem enables you to include an icon next to the Item
  * ‘DefaultItem’ sets the default by Item name Ex: radSplitButton1.DefaultItem = mainItem;

RadRepeatButton provides press-and-hold functionality. While the mouse button is pressed down, the ButtonClick event fires at a pre-determined interval. RadRepeatButton is an ideal UI element for allowing users to control an increasing or decreasing value, such as volume or brightness.

RadToggleButton is designed to manage states on your form. It shares many features with the RadCheckBox, but provides a different visual effect than the standard check mark.

{{tdn:image105.png?180x117|A screenshot of a computer error Description automatically generated}}

===== RadControls – Menus & Toolbars =====

http://www.telerik.com/help/winforms/menus-menu-overview.html

==== RadApplicationMenu – ram ====

http://www.telerik.com/community/forums/winforms/menus.aspx

RadApplicationMenu is the Telerik counterpart of the application menu that displays controls used to perform actions on entire documents and forms, such as Save and Print. It also provides a list of recent documents, access to form options, and the ability to exit the form or application.

{{tdn:image107.png?271x192|A screenshot of a computer Description automatically generated}} {{tdn:image108.png?290x203|A screenshot of a computer Description automatically generated}}

See [[#radribbonbar-rrb|RadRibbonBar]] for more property info.

  * ‘Text’ – shows up on the button itself
  * ‘ButtonItems’ collection defines buttons on the bottom of the dropdown. For example the RadRibbonBar comes with an <Options> button here by default.

==== RadContextMenu – rcm ====

http://www.telerik.com/community/forums/winforms/menus.aspx

To implement context menus use RadContextMenu in your application. RadContextMenu is a non-visual component that sits in the component tray located below the form design surface. RadContextMenu, like RadMenu, can be themed and has an items collection that accepts RadMenuItem, RadMenuComboBoxItem, RadMenuSeparatorItem and RadMenuContextItem.

{{tdn:image109.png?272x247|A screenshot of a calendar Description automatically generated}}

**Create a right click (context) menu.**

Add to a form then link to a control via the control’s ‘RadContextMenu’ property.

Create a [[#_Telerik_Systray_App|Systray app]] menu by binding this to a Windows NotifyIcon (niMain).

RadContextMenuItem – rcmi

> These are the items that appear in the right click menu.

  * ‘Visibiility’ – hide a menu item
  * ‘Enabled’ – set the text to grey and disable user interaction

Use an item as an information display only. You don’t want the highlight on mousehover or the click event to fire, but you don’t want the greyed out text of a disabled control.
<code csharp>
rmiLastSync.Enabled = false; // disable highlight on mousehover and click event
rmiLastSync.UseDefaultDisabledPaint = false; // control is disabled but don't show as grey text
</code>
==== RadContextMenuManager – rcmm ====

[[http://www.telerik.com/help/winforms/menus-context-menu-assign-radcontextmenu-to-telerik-and-non-telerik-controls.html|__http:%%//%%www.telerik.com/help/winforms/menus-context-menu-assign-radcontextmenu-to-telerik-and-non-telerik-controls.html__]]

You can assign RadContextMenu to Telerik and non-Telerik controls. This can be achieved by making use of RadContextMenuManager component. This component will add a RadContextMenu property to all controls on the form. Then, you should simply set a RadContextMenu instance to the RadContextMenu property.

==== * RadCommandBar – rcb ====

[[http://www.telerik.com/help/winforms/commandbar-overview.html]]

RadCommandBar is a fully themeable tool strip that provides unprecedented flexibility. More than just a collection of buttons, RadCommandBar hosts any RadControl, including combo boxes, text boxes, split buttons, drop-down buttons, toggle buttons and more. CommandBar can be moved, rearranged and resized at run time for easy end-user customization.

{{tdn:image110.png?566x65|A screenshot of a computer Description automatically generated}}

Basically a Toolbar. Can add buttons, dropdowns, etc.

[[http://docs.telerik.com/devtools/winforms/commandbar/structure|The structure]] works like this:

  * RadCommandBar
    * CommandBarRowElement - rcbre (1 or more rows)
      * CommandBarStripElement –rcbse (1 or more strips within a row)
        * ‘DisplayName’ is visible to users at runtime in the Overflow button dialog
        * ‘StretchHorizontally’ to make a Strip fill the available width on the Row.
        * RadCommandBarGripButton
        * Items (various)
          * CommandBarButton - rcbbtn
          * CommandBarDropDownButton - rcbddbtn
          * CommandBarDropDownList - rcbddl
          * CommandBarHostItem – can host other controls like date selector or checkbox
          * CommandBarSeparator
          * CommandBarLabel - rcblbl
          * CommandBarTextBox - rcbtxt
          * CommandBarToggleButton
          * CommandBarSplitButton
        * RadCommandBarOverflowButton

**//Select a CommandBarRowElement then click the Task button to ‘Edit Strips’. You can reorder the Strips within a row from this dialog. Choose a Strip to edit, then use the ‘Items’ property to add/edit items. Or can select a Strip directly from the Row and click the Tasks buton to edit only the Items for that Strip. Set the Strip ‘DisplayName’ so it’s visible from the Overflow button dialog at runtime. Set ‘StretchHorizontally’ to make a Strip fill the available width on the Row.//**

RadCommandBar allows the user to show/hide, reorder items and rearrange strip elements on different rows at runtime. ### We need to build a common lib class that saves/restores those customizations. The Save/Load layout functionality gives your applications the opportunity to preserve user settings concerning position, visibility and orientation.

The default icons are all small (16x16) but if you use a bigger icon (32x32 or 64x64) the RadCommandBar will expand as required. You can also force it in code. For example show 32x32 image in CommandBarButton like this:\\  1. Use image with size 32x32.\\  2. Set the MinSize if you want to have space between image and borders of the button.

<code csharp>
this.commandBarButton3.Image = global::CommandBarButtonDefaultSize.Properties.Resources.Button_Next_icon32x32;\\
this.commandBarButton3.MinSize = new System.Drawing.Size(40, 40);
</code>

You can add the items by clicking the down arrow on the RCB, but it’s easier to add and organize if you open the RCB ‘Collection Editor’. You can select multiple items to set common properties.

**Show an icon and text on a control (button, combo, etc) including set button size for text wrap**

//NOTE: You can <Ctrl> click all the buttons to set these properties at once.//

  * **'DrawText' = True**
  * **'TextImageRelation' = ImageAboveText** or ImageBeforeText (for text beside the icon)
  * **‘TextWrap’ – True** if long text. Also set:
    * **‘AutoSize’** = False
    * **‘Size’ = 55,65** for 32x32 image. Adjust as required.
  * **‘DisplayName’** – //Be sure to set this one equal to the text property or it won’t have a real name in the toolbar configuration control (from RadCommandBarOverflowButton).//
  * ‘Image’ – clear to remove the icon, or set to a desired icon image
  * ‘visible’ = false to hide the commandbar collapsing the space it occupies
  * CommandBarRowElement (Rows Collection) – a horiz or vert row where a StripElement (toolbar) is shown
  * CommandBarStripElement (Strips Collection) – basically a single, draggable toolbar on the CommandBar (which can hold multiple toolbars)
  * DisplayName – The name shown to the user for a StripElement or subcontrol the user sees when customizing the toolbar at runtime.
  * RadCommandBarGripButton
  * Orientation - the orientation in RadCommandBar can be set via the Orientation property:<code csharp>
radCommandBar1.Rows[0].Strips[0].Orientation = Orientation.Vertical;

    * **CommandBarDropDownButton** – rcbddbtn (Drop down items are rcbddbtni )
      * ‘Text’ – the text on the button

        * Set the DropDownButton ‘Text‘ to the default value you want to display.
        * Add all the DropDownButton ‘Items’ and set their ‘Text’ properties to the text you want to display if they are selected. Make note of each time control name.
        * You have to add a Click Event to each DropDownButton Item (not the parent DropDownButton itself). Use the VS Property Grid dropdown to find each Item (that’s why we remembered them before). Then add a Click event. Here’s a couple of examples of click events that change the Text property on the CommandBarDropDownButton parent control.
        * <code csharp>
// 'Show entire event' Entire vs. Entry Only drop down button

Other controls, like the top of a RadPanel, can appear behind a RadMenu. I’m not sure how to force them both to the same layer, but you can use the Margin – Top to push the hidden control down. Look for a better solution. **The best thing to do is to add the panel after the RadMenu. //Also look to my instructions on RadCommandBar to deal with controls behind this one.

RadMenuButton – rmb

Menu child items are under the RadMenu.Items (Collection). Then select a child and look to its RadMenu.Items (Collection) for the grandchildren items.

  * ‘Visibility’ – hide a menu item

With the RadRibbonBar control you can build user interfaces similar to those used in Microsoft Office.

{{tdn:image119.png?383x309|A screenshot of a computer Description automatically generated}}

**//Consider adding a [[#_RadRibbonForm|RadRibbonForm]] to the Solution rather than adding a RadRibbonBar to a regular RadForm.//**

  * The StartButtonImage property specifies an image to use for the <Start> button in the upper left corner of the control.
  * **‘CommandTabs’ collection defines the ‘RibbonTab’ tabs across the top**
  * ‘contextualTabGroup’ collection defines areas across the top of the form. I assume to control tab visibility by context.
  * ‘QuickAccessToolbarItems’ collection defines QAT items
  * ‘StartMenuItems’ collection defines the items under the round <Start> button.
  * ‘StartMenuRightColumnItems’ collection defines the items in the right column under the round <Start> button.

**RadRibbonTab – rrbt**

  * ‘Items’ collection defines ‘RadRibbonBarGroup’ items - button container groups on the current RadRibbonTab

RadRibbonBarGroup – rrbg

  * ‘Items’ collection defines ‘RadMenuItems’ (controls - buttons, etc) or ‘RadRibbonBarButtonGroup’ containers which include a border and allow vertical orientation.
  * Set Buttons for AutoSize = False, TextWrap = True and set Size/Width = narrower so the text will wrap
  * <color red>I’m not sure how to center buttons in a group when the group name is wider than the list of buttons.</color> 

RadRibbonBarButtonGroup – rrbbg

  * ‘Orientation’
    * ‘Horizontal’ default. Controls side by side.
    * ‘Vertical’ Allows you to stack controls vertically
  * ‘Items’ collection defines ‘RadMenuItems’ (controls - buttons, etc)

**RadButtonElement - rbe - Position text to BottomCenter, enable TextWrap and config an icon**

  * Select one or more buttons and set ‘TextAlignment’ = ‘BottomCenter’
  * By default the text sets the button width, but you probably should set size manually. These are good defaults:
    * AutoSize = False
    * TextWrap = True
    * Size/Width = small enough to wrap the text to 2 lines (assuming you also want a small icon).
    * Size/Height = 66 is a good default. 68 starts to push down the ButtonGroup label but is an acceptable max.
    * TextImageRelation – ImageAboveText
    * TextAlignment = BottomCenter.
      * <color red>Dealing with buttons with both 1 and 2 lines of text. Maybe better than above, use bottom padding to push single line text up from the bottom. Turn on TextWrap. Set button size to X,66, where x is the width that forces any required text wrap. Set Padding.Top to 2-8 to push the icon down and Padding.Bottom to 0 for buttons with 2 lines of text and 15 for buttons with 1 line of text.</color>
  * ‘Image’ = ??? to set the icon graphic image. Choose “Local resource” | <Import> | browse for graphic and finish. RibbonBar icons should be 32x32 pixels.
    * ‘ImageAlignment’ = TopCenter
    * Padding/Top = 8 (or so) to push the graphic down to the center of the button (assuming the above sizes)

**Hide elements of the Ribbon Bar**

Add the following code right under ‘InitializeComponent();’ in frmMain() (or whatever the form is called).
<code csharp>
// Stick this right after “InitializeComponent();” on the form
// Hide the AppButton (Office Start button or 'File' tab) on the RadRibbonBar
radRibbonBar1.RibbonBarElement.ApplicationButtonElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;

// Hide the QAT (Quick Access Toolbar) on the RadRibbonBar
radRibbonBar1.RibbonBarElement.QuickAccessToolBar.Visibility = Telerik.WinControls.ElementVisibility.Hidden;

//Hide Title Bar - collapse all 3 elements to hide this bar
richTextEditorRibbonBar.RibbonBarElement.QuickAccessToolBar.Visibility = ElementVisibility.Collapsed;
richTextEditorRibbonBar.RibbonBarElement.ApplicationButtonElement.Visibility = ElementVisibility.Collapsed;
richTextEditorRibbonBar.RibbonBarElement.RibbonCaption.Visibility = ElementVisibility.Collapsed;

// Hide any RibbonBar tab with 'Name' = "Hidden" or where 'Text' contains "Hidden" (just the tab, not content)
foreach (Telerik.WinControls.UI.RibbonTab item in radRibbonBar1.CommandTabs) {
  if (item.Text.ToLower().Contains("hidden") == true || item.Name.ToLower().Contains("hidden") == true)
    item.Visibility = Telerik.WinControls.ElementVisibility.Hidden; %%//%% sometimes ‘Collapsed’
}

// Shift Tab Groups to the left when the AppButton (Office Start button or 'File' tab) is collapsed
radRibbonBar1.RibbonBarElement.ApplicationButtonElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
Padding p = radRibbonBar1.RibbonBarElement.TabStripElement.ItemContainer.Padding;
radRibbonBar1.RibbonBarElement.TabStripElement.ItemContainer.Padding = new Padding(0, p.Top, p.Right, p.Bottom);

// Hide the ‘ribbonTab1’ tab on the RadRibbonBar  
ribbonTab1.Visibility = Telerik.WinControls.ElementVisibility.Hidden; // sometimes ‘Collapsed’

// Hide the Caret button in the upper right that collapses the RibbonBar
this.radRibbonBar1.RibbonBarElement.ExpandButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

// Select the 1st tab [0] on the RadRibbonBar by default
((Telerik.WinControls.UI.RibbonTab)radRibbonBar1.CommandTabs[0]).IsSelected = true;

==== RadShortcut (Hotkeys) ====

http://docs.telerik.com/devtools/winforms/shortcuts/shortcuts-overview

Almost each application uses the so-called “Shortcuts” – a keyboard combination that triggers a specific action. For a valid shortcut is considered any keyboard combination where a Modifier Key (Ctrl, Alt and Shift or a combination of these) is down and other key(s) is pressed. This semantic is available out-of-the-box in our framework and allows you to seamlessly plug any valid keys combination as an action accelerator. Supported are also the so-called multiple keys shortcuts where the Keys member of each shortcut may be more than one key – e.g. Ctrl + A, S is recognized by the framework. Shortcuts without modifier keys are also supported, but they should be used with caution, since they may be in conflict with other controls which intercept keyboard input.

RadDesktopAlert component displays a small pop-up window on the screen to notify the user that a specific event has occurred in the application.

{{vertopal_daaeffda7d704b80a16bba19fb3588e8/media/image45.png?294x96|A white and green background with black text Description automatically generated}}

My sample project: [[file:///\\192.168.93.1\KB_MiM\Telerik\LS.TelerikSystrayApp|\\192.168.93.1\KB_MiM\Telerik\LS.TelerikSystrayApp]]

Popup notification similar to Outlook’s you have a new email Notify (Notification) popup. You can drag it around the screen. There are three buttons in the upper right to close, pin it to the screen and display a list of options.

For multi-monitor systems use the SetActiveScreen() method of the DesktopAlertManager class to set the screen where alerts display at ‘ScreenPosition’.

You can display multiple alert instances on the screen and the DesktopAlertManager will calculate the alerts’ location so that they do not overlap. Alerts are stacked on the screen in the order of their appearance. When an alert is closed, all related visible alerts are automatically relocated to utilize the screen real estate. To show multiple desktop alerts you must create a new instance for every alert. To replace an alert dispose the instance and create another new one.

int i ; %%//%% create multiple instances of the

for (i = 0; i <= 2; i++)

{

RadDesktopAlert a = new RadDesktopAlert();

a.CaptionText = i.ToString();

a.Show();

}

RadDesktopAllert does not support auto-size mode. You must set the size of the control so your contents will fit.

You can add a button (or other element) to any control, including an Alert. Here’s how to add a button:\\
RadButtonElement element = new RadButtonElement();

element.Text = "Button";

element.MaxSize = new Size(20, 20);

this.radDesktopAlert1.Popup.AlertElement.ContentElement.Children.Add(element);

//You can Preview the Alert in the IDE from the control Smart Tag in the Component Bin.//

  * ‘ScreenPosition’ accepts six possible positions from the AlertScreenPosition enumerator: TopLeft, TopCenter, TopRight, BottomLeft, BottomCenter, BottomRight
  * ‘FixedSize’ defaults to 0,0 for a default size. Set this to override the size, or do it in code:\\
this.radDesktopAlert1.FixedSize = new Size(200, 200);
  * ‘CanMove’ default True, enables the Alert to be dragged with the mouse
  * ‘AutoCloseDelay’ how long to stay on screen (defaults to 10 sec)
  * ‘AutoClose’ whether will disappear after the period of time defined by the property. Set = false to leave open.
  * ‘AlertImage’ specifies an icon that will be shown on the left of the alert panel
  * ‘ButtonItems’ collection adds custom buttons to the alert
  * ‘Opacity’ starting opacity when it appears (defaults to 0.8 – 80%). Changes to 100% on mouse over.
  * ‘PopupAnimation’ = true to enable animations
    * ‘PopupAnimationFrames’ number frames in the popup animation. More frames means longer animation.
    * ‘PopupAnimationDirection’ (default Down) direction of the animation. Down slides down from the initial location. Can aldo have Up, Left or Right.
    * ‘PopupAnimationEasing’ different animation easing effects which are used to start and finish the animation.
  * ‘FadeAnimationType‘ (default ‘FadeIn,FadeOut ‘)accepts values from FadeAnimationType enum which also allows for combinations of its values.
  * You can also use the FadeAnimationFrames property to define the amount of frames used to animate the opacity of the alert’s popup. By increasing the amount of frames you will increase the duration of the fade animation.
  * Caption Buttons
    * ‘CloseButton’ closes the alert. Use ShowCloseButton to show/hide the button.
    * ‘PinButton’ pin the alert on the screen and prevent it from being closed automatically. ShowPinButton to show/hide the button.

  * 'Size' \Layout
  * Multiline RadLabel - Set 'Auto Size' = False and ‘TextWrap’ = True. Then go directly to the 'Size' and enter 50,50, or you can drag the box size. Don't embed \n in the text. Or dock the label to a container to set the size.

Custom Text Formatting via MarkupEditor

http://www.telerik.com/help/winforms/panels-and-labels-label-html-like-text-formatting.html

  * For example making one word in a sentence bold. Click the down arrow on the 'Text' value and click <Start MarkupEditor>.
  * Use <Shift><Enter> for new lines. It will generate HTML. The font changes made here (color, etc) are not the same properties as those in the Properties window.

=== Hyperlink to a function in the application ===

Set these RadLabel properties and double click the label to stub out a click event.

  * ‘ForeColor’ = ‘HotTrack’ - a blue visible under the color dropdown ‘System’ tab
  * ‘Underline’ – ‘True’

=== Hyperlink to website in default browser ===

Instead of LinkLabel see the <Links> button on the ‘MarkupEditor’ behind the ‘[[#radlabel-rlbl|RadLabel]].Text’ property dropdown and open locations without additional code.

  * Choose link ‘Type’ of ‘http:%%//%%’ or ‘https:%%//%%’ and enter a web url there and the link works with no extra code. The .Text generated markup looks like this:

> <html><a href="http:%%//%%www.legalitysoftware.com/">Legality Software</a></html>
> 
> <a href="http:%%//%%www.legalitysoftware.com/"><span style="color: #d86040">Legality Software</span></a> - orange font in Wizards (NOTE: Set ‘BackColor’ = 225, 228, 240 to match wizard form)
> 
> <html><a href="http:%%//%%support.lawtopia.net/">View log files</a></html>

  * Choose link ‘Type’ of ‘mailto:’ and enter an email address to open an email in the default client.
  * Choose link ‘Type’ of ‘(other)’ and enter a local file path to pop the Windows Explorer in the location.. The .Text generated markup looks like this:

> <html><a href="file:%%//%%/C:/DevGit">View log files</a></html>

  * Make only part of the label a clickable link like this:

> <html>Click this <a href="file:%%//%%/C:/DevGit">View log files</a> to open Windows Explorer</html>

> The ‘WaitingBarIndicatorElement’ is the sliding part, which has:

  * Its own ‘.Text’ property making the text scroll with the colored highlight.
  * ‘ShouldPaint’ which hides the slider (even though it still moves) returning the waiting bar to a solid color – use this and the StartWaiting()/StopWaiting() methods to indicate the process is finished. //See note below about multiple elements…//

RadTitleBar control is used in forms and provides functionality for dragging, minimizing, maximizing and closing the form. This control is internally used by RadForm.

To include a title bar with help, maximize, minimize and close button functionality simply drag it from the toolbox on the desired form. This control is great addition to the ShapedForm.

To customize the help, minimize, maximize and close buttons, use the RadTitleBar.TitleBarElement's HelpButton, MinimizeButton, MaximizeButton and CloseButton objects. Each button is a RadButtonElement type that include properties to control text, image, and layout.

http://www.telerik.com/community/forums/winforms/track-and-status.aspx

http://www.telerik.com/help/winforms/track-and-status-controls-scrollbar-getting-started.html

Using Telerik scrollbars is a bit more intricate compared to using the standard scrollbars because you have to handle scroll event manually. Add a RadPanel to your form then add a RadVScrollbar in the panel and dock it to the Right. Add another RadPanel inside the 1<sup>st</sup> RadPanel and set its height to the total height you want to be available upon scrolling (taller than the 1<sup>st</sup> RadPanel). This value can be statics e.g. 1000 pixels or dynamic determined by the scrollable content. Now add controls (the controls which are to be scrolled) to the second RadPanel.

{{vertopal_daaeffda7d704b80a16bba19fb3588e8/media/image55.png?192x172|A white background with black squares Description automatically generated}}

Then subscribe to the Scroll event of the vertical scrollbar and assign its negated value to the Top property of the second RadPanel:

void radVScrollBar1_Scroll(object sender, ScrollEventArgs e)

{

this.radPanel2.Top = -this.radVScrollBar1.Value;

}

Finally, set the Maximum property of the scrollbar to reflect the size of the scrollable height which is the total height of the scrollable content minus the visible height. For the example of this section in particular, that is the height of the second panel minus the height of the first panel.

this.radVScrollBar1.Maximum = this.radPanel2.Size.Height - this.radPanel1.Size.Height;
