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.

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?
