You can use the OnItemClick
event to persist the currently displayed rotator item when the control is updated via a postback.
If you are using the RadAjaxManger and the rotator is reloaded, most probably it is included in the partial updates that are initiated by the control. Please check its documentation
and ensure that you have configured the AJAX request triggers and the updated controls correctly.
If the difficulties persist, please send a simple, fully runnable page that shows your setup so that I can inspect it and suggest a concrete solution.
