Hi Guys, I am having a strange problem which I tried searching here on the forums. I am binding around 27000 rows synchronously (tried Virtual) to a UltraWebGrid with page size 50 and tried without. The data loads eventually which is expected, this is a lot of rows, each having 3 columns. The problem comes in when I try browsing to the next page or double clicking on one of the items. The page is hit but soon gives me a stack overflow exception. Can anyone give me advice on this? If the data is 1 or two records it works fine in paging or non paging mode. This would point to data sizing. Regards.
