It looks like you don't want to make any change after you make any change in gridview, right ??

that didn't work .... i have a DataField="AssignID" also used in gridview

protected void AssignmentGrid_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int index = Convert.ToInt32(e.RowIndex);
AssignmentGrid.DeleteRow(AssignmentGrid.SelectedIndex);

}

First get all the data in some collection, let's say, in a List<t></t>.

Assign this List as a DataSource to the Gridview.

And perform the operations like, INSERT-UPDATE-DELETE on this List<t> and then again bind it to the Gridview.

I don't have any working example, so I can't explain it through it. But yeah, I have done this a while ago, and worked properly.

Remember, all you have to do is, play around the List<t> rather than Database :)
