I have the same problem. I bound the grid with a costum object collection (above 1200 items with 12 properties) and I really have bad performance when I scroll down.
I tried the UIVirtualizationMode solution and it doesn’t change anything.
I also have no event defined, so, I realy have no idea of what I can do to have better performance.
