Getting delta between results of the same data page
I have a repeat grid having a data page as source as the attached shows, I have the following requirement:
if the user go back to this grid and modify it by unchecking/checking values, I need to detect the delta betweeen the current data page and the old one, I have tried using CompareTwoPageLists , but, it didn't work as the current and the new data pages are the same, so result is 0.
How to achieve that?
thanks in advance,
