<telerik:RadComboBox AutomationId="staticItemsComboBox">
<telerik:RadComboBox.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>USA</x:String>
<x:String>Uganda</x:String>
<x:String>Ukraine</x:String>
<x:String>Canada</x:String>
<x:String>France</x:String>
<x:String>Italy</x:String>
<x:String>United Kingdom</x:String>
<x:String>China</x:String>
<x:String>Japan</x:String>
</x:Array>
</telerik:RadComboBox.ItemsSource>
</telerik:RadComboBox>
Here is the result:
