Hi guys
I have enabled Automatic edit delete and insert in radgrid with sql data source. I have an external filter (radcombo) for filtering radgrid with distinct values of first three columns. Everything is working properly. But my issue is after filtering edit is not working properly. When i click on edit image button on a row in filtered grid i am getting first row in that grid instead of clicked item. I think, when i click on edit button radgrid going back to previous data source. How can I edit that particular clicked row in that grid. Here is my code. Please help anybody to clear this issue.

Hi Ben,

Indeed, RadGrid is rebound when its items are going in edit mode. However you are setting the new SelectCommand on SelectedIndexChanged of the combo, on the next postback, the SelectCommand is the old one. To overcome the issue you can try setting the SelectCommand on Page_Load to the desired one.
