I have a grid with about 1,000 records and then grouped - the largest group has about 580 records in it. When I click on the group heading to expand this group it is very slow (over 1 to 2 seconds). The grid has 16 columns in it. When I make the window smaller (i.e. only a smaller portion of the grid is visible) this reduces the time to expand the group.
Can you suggest any likely causes for this behavior and/or any ways to optimize it
Thanks
