This functionality can be achieved with the RadRotator for ASP.NET AJAX as well. The online demo Pager Integration
show how to add a pager to the RadRotator. The items of the pager can be customized to look as required in your scenario, the essential part is to call client-side method of RadRotator set_currentItemIndex(index)
to display the selected rotator item when a pager element is clicked. Then you can implement the auto scroll functionality via the client-side scripts from the demo Client-side API
I hope this helps. Let me know if you need further assistance.
