I am using Advanced databinding method. When yapAfter button is clicked I add an item to my List stored in the session according to the specific index and I rebind my List. Also in NeedData Source event my List stored in the session is binded. There is no problem when Allowpaging is off in Listview. However when I turn on Allowpaging the items I added last to my List comes out at the beginning of the List. They are not listed according to the Index I assigned while adding.

Thanks,
Regards.
