SIlverlight: how to add scrollbars to ItemsControl?

Ok, maybe it's ridiculously simple, but all the time I has to stop and think about it! Here is the solution:

<ItemsControl ItemsSource="{Binding MyItemsSource}">
       <ItemsControl.Template>
            <ControlTemplate>
                 <ScrollViewer x:Name="ScrollViewer">
                     <ItemsPresenter />
                 </ScrollViewer>
            </ControlTemplate>
       </ItemsControl.Template>
</ItemsControl>
