Hi,
I have a grid that is populated in the event NeedDataSource when the page is loaded. When selecting an item from a combo, the other is a populated combo, and now gives an error 500.
I did several tests and when I populate the grid with up to 41 records, works, but if my grid has more than 41 records this error occurs ...
This grid has image and textbox in the ItemTemplate ...
Can anyone help me urgently?
Error:
