# Getting Started with WinUI GridSplitter

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>
```
