Hello,

In each Insert,Update or Delete operation, you can identify the currect to on server side with AddRow,DeleteRow, and UpdateRow server side event. You can look into e.Row properties.

Yes, that was helpful. But is not there a way where on click of some button placed out side the grid i can get list of such modified rows ? 

Or as you mentioned the only way is to mange list of such rows on my own ?

Hi,

Unfortunately, It could not be done via button click.  
Insert,delete and update operation have already finished before clicked the button.
That's why when we tried to get changes or cahce, they will always return null.

The possible way, you will need to manage the list manually.
My suggestion, you can save each modification in each event which I already told you into some hidden fields. When you clicked a button, you can load the saved list. Hope this helps.

Handy
