You should not call the RegisterAsynchronousPostBackControl method of the ScriptManager class. This method instructs a control to always perform an asynchronous post back.

You should not call the RegisterRequiresPostBack method of the Page class. This method instructs the page processor to call methods of the IPostBackDataHandler interface implemented by a control when a page post back occurs. It does not matter whether the post back is a full post back or an asynchronous post back.

You should not call the RegisterRequiresRaiseEvent method of the Page class. This method instructs the page processor to call the RaisePostBackEvent method of the IPostBackEventHandler interface implemented by a control when a page post back occurs. It does not matter whether the post back is a full post back or an asynchronous post back.
