Here's an idea for you, one which I haven't fully thought through but which I will post here in case it proves useful.
For my use case we am required to build the Telerik UI for WPF binaries from the source code. This is because we offer our product as a trial version which requires the source files to be protected.
Building the source takes a bit of time whenever there is a new version and we have to remember to copy and replace the modified source protection files before we build the binaries.
My suggestion would be to move the file protection code into a single separate class library (DLL) and provide the source code that can be modified by the end user and rebuilt into the file protection DLL.
Then rather than having to rebuild the entire source code from scratch whenever there is a new version, we could just use the installer to install the new binaries and just replace the FileProtection.dll file.
That way when there is a new version of UI for WPF (or whatever product) we could quickly update to it and then when we build our product installer we just copy the modified FileProtection.dll to be bundled alongside the Telerik binaries.
As I said I haven't thought this through all the way and there may be excellent reasons why you are unable to do this, but I thought I'd share the idea.

In our app many checkboxes are crop when user scale to 125 %, it happens in win11 but it has been reported in win10.
I found out that this is also happening in the colour theme generator from Telerik with the checkbox in the ribbon (screenshot below).
Is this a known issue or something that we can fix some how? so far we have taken the template for the checkboxes and change the margin of the element "grid" from 1 to 0 to work around it.
Thanks in advance

If the total Items count exceed the MaxVisiblePips value,scroll by mousewheel,when scroll to the start or end item,the next scroll item should be the end or start,
the scrollview can not scroll to the selected item. Please see Annexes 1 and 2
When the MaxVisiblePips value is four,click the right item ,The scroll view cannot be rolled to the center, Please see Annexes 3
Since we are working with large TreeViews users some times get confused about the current parent of an Element.
It would be useful if the parents of on element would sticky to the top of the control.
Similar to functionatlity of the Sticky Group Headers for the RadGridView or the newly introduced Sticky scroll in Visual Studio

Develop a new control - Fisheye Panel.
New control request: FishEye menu.
A new Tag Cloud control similar to the WinForms and ASP.NET Ajax counterparts (http://demos.telerik.com/aspnet-ajax/tagcloud/examples/overview/defaultcs.aspx)
Create a SlideView control like the one in the Telerik UWP suite.
https://docs.telerik.com/devtools/xamarin/controls/slideview/slideview-getting-started
The control should have a content area, previous and next buttons, and dots indicator below, that indicates the currently selected page.
If a formula contains a named range as an argument, its value may not get updated properly in the following scenario:
In the formula: =SUMIF(A1:A4, 3, ColumnC), ColumnC is a named range refering to C1:C4. Range A1:A4 contains the values 3, 2, 2, 3, which will avoid a circular reference. The formula is entered twice, in C2 and C3. Note that these cells are part of the range ColumnC refers to. When you refresh the formula in C3 (enter edit mode, then press enter), it will calculate correctly, but the formula in C2 will be recalculated to an error. If you refresh the formula in C2, the formula in C3 will be evaluated to an error.
I use RadWindow as the main window for my application (primarily because I want to embed a menu in the title bar). This works well except our users have reported a bug where they are unable to use hotkeys following activating the application from the TaskBar.
A typical scenario:
* minimise the application using the minimise button
* some time later, activate the app by clicking on the TaskBar icon
* Press CTRL+N hotkey combination which should execute a command
I have created a sample application that shows two windows: a regular Window and a RadWindow. They both contain input bindings for the Ctrl+N combination. When the regular window is activated from the taskbar, the input bindings work, but when the same sequence of events is performed on the RadWindow the input bindings do not work. Clicking between the windows does work - it seems the problem is only related to application activation.
On a related note, both windows contain a TextBox control. If text is highlighted in the regular window, the highlighted text is maintained and redisplayed when the window is activated. This does not work for the RadWindow. As it relates to keyboard focus, I wonder if the problem is related.
i hope add char controls

I want to be able to specify the font family, size, etc. from XAML, not from code. Exactly the same as described here: https://www.telerik.com/forums/implicit-styles-custom-font-and-font-size (background: We are developing a UI Framework + resource dictionary for use in different applications. If each app will have to modify font sizes from code, inconsistencies are surely happen)
