Getting Started with WinUI GridSplitter

Updated on Mar 26, 2026

This article will guide you through the steps needed to add a basic RadGridSplitter control in your application.

Assembly References

In order to use the RadGridSplitter control, you will need to add references to the following assembly:

• Telerik.WinUI.Controls
• Telerik.Licensing.Runtime.dll

Adding RadGridSplitter to the Project

You can add a RadGridSplitter manually in XAML as demonstrated in Example 1.

You can access the RadGridSplitter control through an alias pointing to the Telerik.UI.Xaml.Controls.Primitives namespace: xmlns:primitives="using:Telerik.UI.Xaml.Controls.Primitives"

Example 1: Adding a GridSplitter control to a Grid

XAML

<Grid>
	<Grid.ColumnDefinitions>
		<ColumnDefinition/>
		<ColumnDefinition Width="Auto"/>
		<ColumnDefinition/>
		<ColumnDefinition Width="Auto"/>
		<ColumnDefinition/>
	</Grid.ColumnDefinitions>
	
	<Border Background="#CCD15C" />
	<primitives:RadGridSplitter Grid.Column="1" />
	<Border Background="#81BCD1" Grid.Column="2" />
	<primitives:RadGridSplitter Grid.Column="3" />
	<Border Background="#C89745" Grid.Column="4" />
</Grid>
