Pagae events in asp.net 2.0

fAfter searching through internet i found good use of PreRenderComplete event is modifying the result of databinding. I will explain more clearly for suppose if u want to add a menu to sitemapdatasource after databinding. if you do it in prerender event it will erased. if you need to append an item to the menu dynamically, you can do it in prerendercomplete event.
