What I do is set the data initially, then cache the existing setup in a 
local array. When something changes I can examine the array, make the 
necessary changes, and update only the changed data in the datagrid. 
This makes a huge difference in response time, especially when I'm 
storing thumbnail images in the datagrid and I really don't want to have 
to calculate thumbnails for each cell in the grid a second time.
