I have a product entry screen where the items in the order are displayed inside a repeater control within an ajax update panel. The repeater simulates a grid where every row is editable at once (so user can tab through the rows, updating many quantities, and then hitting one save button at the bottom).
Right now it works, but is a little too slow (way too slow over 100 items). The repeater will have anywhere from 20-250 rows. Is there a way to not have the entire repeater re-render when I just want to add one row?
