Hi, the new feauture Merge Cells is very nice but the alignment is only at the center.

Can I align the merged cells in the same mode of the column?

Thanks, Fabrizio

When I update to version 2024.3.806 I get a build error :

Please consider integration / enhancement of the following rich sting rendering capabilities enabling performance for quick rich string related rendering tasks, providing further alternatives to GDI and GDI+ based tiresome and limited solutions, allowing scaling: https://github.com/toptensoftware/RichTextKit

 

 

Set IsThreeState property to true and choose ToggleState to Indeterminate.

I would like to see a new property added to the RadLabel control: Style. Style is an enumeration with layout styles like in MS-Word: 

• Normal
• Title
• Heading 1
• Heading 2
• etc.

When the style is applied, the styling (font, color, background, etc.) is applied conform the currently active Theme. Therefor all themes need to be expended to support this setting.

Of course the enum label 'Custom' should be present (or null) when a user tries to override the style-related properties (like font, color, background, etc.)

This is very usefull when a programmer wants to build his own form (with or without Layout / Flow controls).

Telerik already uses it a bit themselves: Some (data entry) controls already generate (group) headers and captions in there forms. 

The AccessibleObjects in NetCore have ComVisible=False and this causes a handled exception. This attribute is not required in NetCore and could be removed.

Hello there,

I am facing system.StackOverflowExcepiton while exporting document with HtmlFormatProvider. I am attaching my code with the HTML string which I am passing into RichTextEditor.

HTML String:

When trying to open the QuickStart solution from 

C:\Program Files (x86)\Progress\Telerik UI for WinForms 2025 Q1\Examples

installation folder, the following error appears:

I've tested this with both Telerik.WinControls.UI.RadForm and Telerik.WinControls.UI.RadRibbonForm

Telerik.WinControls.UI.RadForm works fine!  Telerik.WinControls.UI.RadRibbonForm fails to bubble up Keys.Up, Keys.Down, Keys.Left and Keys.Right

 

Steps:

Create new WinForms project (I'm using .net 4.7.2)

Add Telerik extensions. 

Add a Form (Windows Form default .Name = "Form1"), RadForm (default .Name = "RadForm1") and RadRibbonForm

You can use any Theme or default.  Makes no difference.

 

Set all three form's .KeyPreview = True

Add this method to each form:

Private Sub form_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Up Then
If My.Computer.Keyboard.ShiftKeyDown Then
MsgBox("Shift Up")
Else
MsgBox("Up!")
End If
End If
End Sub

Set your Startup Form = Form1 (The Windows Form) and click Start.

hit your UP-Arrow key.  You'll get the MsgBox "Up!"

Hold shift+UP-Arrow and you'll get "Shift Up"

The above is True for Winforms AND RadForm but RadRibbonForm does this:

 

Set your Startup Form = radribbonform and click Start

Hit your UP-Arrow and you'll get...nothing.  The event never gets raised.

Hold your shift+UP-Arrow and you'll get....nothing because the event does not fire when you hit any of the arrow keys.

 

 

 

 

 

RadMessageBox(form) is a telerik replacement for the System.Windows.Forms.MessageBox.

MessageBox has a parameter MessageBoxOptions.DefaultDesktopOnly which makes it (surprisingly) topmost. RadMessageBox does not have this option.

I have a scenario where the RadMessageBox is hidden by a total different application when shown. So I need to make it topmost.

Can you add some kind op RadMessageBoxOptions to make it topmost?

Using specifically Win11 Compact DARK theme has additional space compared to the Win11 Compact LIGHT theme. See the pictures.

• On Light theme there are 4 pixels between the form border and the top border of a tab.
• On Dark theme there are 12 pixels between the form border and the top border of a tab.

In my opinion the dark theme has a wrong height here and the light theme is correct, especially compared to other themes, even Office 2019 for example.

Light theme:
