Hello everyone,

Here are the highlights of the new online resources we published this week from 29 Oct 2025 to 05 Nov 2025:

Article: https://www.telerik.com/products/wpf/documentation/netcore/overview
Summary: This article shows you how to use Telerik UI for WPF in .NET Core/.NET SDK-style WPF projects, outlining supported target frameworks and the Windows-only scope. You add the Telerik packages from your private NuGet feed, reference the controls and XAML namespaces, merge theme resource dictionaries, and account for Visual Studio design-time support and differences from .NET Framework.

Article: https://www.telerik.com/products/wpf/documentation/security/overview
Summary: This article outlines the Telerik UI for WPF security model: assemblies are strong-named and Authenticode-signed, and the controls are designed for full-trust desktop applications rather than partial-trust environments (e.g., XBAP or partial-trust ClickOnce). It provides guidance to reduce risk—avoid loading untrusted XAML or documents, gate clipboard/drag-and-drop/printing/file access, keep dependencies updated, and align your app with .NET/WPF security practices.

Feel free to check them out and share your thoughts!

The RadWebCam for WPF control currently relies on the SharpDX library to render the video feed. With 2024 Q4 we will replace SharpDX with the SkiaSharp library. This decision was taken because the SharpDX library is no longer maintained since March 2019.

As of 2024 Q4 (November), we will deprecate the .NET 7 distribution. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.  

We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post: Product Update for Enhanced Performance and Security

For more information about how to upgrade your project when a new version of the Telerik UI for WPF suite is released, you can check here: Project Migration to .NET 4.6.2 and .NET 6

Good morning,
I can't figure out how to change the GridView style in the RadMultiColumnComboBox WPF. I'd like to change the text in the column header, for example, or the alternating columns, but I can't figure out how. I have the 2022 version of Telerik 2022 R3 SP1. I hadn't had any problems with WinForm, but I'm having some difficulty with WPF. Can someone tell me how to do it?
Thanks

Good morning,
Is it possible to remove the ClearButton from the RadMultiColumnComboBox so that I can select and copy text into the RadMultiColumnComboBox's text field with ctl + c?
I have Telerik 2022 R3 SP1 and I can't figure out how to do it. It's easy with RadComboBoxes; is it possible that this isn't possible with the RadMultiColumnComboBox?

Hi There
Currently I have on my project an Assembly reference to the telerik DLL
This is causing troubles in the development group, some has a different version, others a different configuration of the environment
There current reference is as
<Reference Include="Telerik.Windows.Controls">
  <HintPath>$(TelerikBin)\Telerik.Windows.Controls.dll</HintPath>
</Reference>
but I like to migrate to a NuGet instead so the component is in the project and is more transparent for everyone.
Problem I encounter is that there are multiple
Telerik.Windows.Controls.for.Wpf
Telerik.Windows.Controls.for.Wpf.Xaml
I try them both but my problem persists.
The Textboxes disappear from the forms.
Is there a simple and transparent way to migrate from the DLLs to the NuGets?

Goodmornig

Is it possible to set the WPF RadGridView FilteringMode="FilterRow" so that the search updates in real time as you type the text, like it was in winform?

And also that it uses the "contains" mode by default without having to select it from the menu every time, like it was in winform?

Thanks

Hi,

Is this large number of PriorityItem<DispatcherOperatio> which is more than 373K normal in RadGridView? Why is this happening? Is there anyway to stop the propertyChangedCheckerTimer created by default in RadgridView?

Version: 2017.2.503.45

What does this mean? I think it means I'm not logging in for builds, but I put in the right username\pwd. Why is this showing up?

"c:\code\Avanti15\Applications\Operations\ShopFloor\ShopFloor_fq4img1v_wpftmp.csproj" (_CompileTemporaryAssembly target) (83) ->
