I can’t get this to work. I can bind items to a listbox in the same way without problem…
<telerik:RadDocking DataContext="{Binding Source={StaticResource CustomerViewModel}}">
<telerik:RadSplitContainer ItemsSource="{Binding Path=Customers}">
<telerik:RadSplitContainer.ItemTemplate>
<DataTemplate>
<telerik:RadPaneGroup >
<telerik:RadPane Header="{Binding Path=CustomerName}">
</telerik:RadPane>
</telerik:RadPaneGroup>
</DataTemplate>
</telerik:RadSplitContainer.ItemTemplate>
</telerik:RadSplitContainer>
</telerik:RadDocking>
