# Getting Started with WinUI SegmentedControl

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

## Assembly References

To use the **RadSegmentedControl** suite in your projects, you have to add references to the following assembly:

* `Telerik.WinUI.Controls.dll`
* `Telerik.Licensing.Runtime.dll`

## Defining a RadSegmentedControl

The control allows you to work with two types of data - string and image. You can use the **ItemsSource** property of RadSegmentedControl to provide **IEnumerable** collection of strings or image sources. The control will display a segment for each item in the items source.

> You can access the RadSegmentedControl control through an alias pointing to the Telerik.UI.Xaml.Controls.Input namespace: xmlns:input="using:Telerik.UI.Xaml.Controls.Input"

Here is an example how to set the control's ItemsSource property and populate it with some data.

#### **Example 1: Defining a RadSegmentedControl**

```XAML
<input:RadSegmentedControl x:Name="segmentControl" VerticalAlignment="Center" Margin="20"/>	
```

#### **Example 2: Settings ItemsSource**

```C#
public Getting_Started()
{
	this.InitializeComponent();
	this.segmentControl.ItemsSource = new List<string>() { "Popular", "Library", "Playlists", "Friends" };
}
```

This is the result:
