[amily]

Hi All,
I made a page in asp.net to edit information in the database using gridviewcontrol. It was working fine. Then i entered the template column having dropdown list. now the page opens and and i edit information, When I press update, it gives me an error, "No value given for one or more required parameters". I checked the forum for previous such problems, but didn't help much. Kindly help me.......

Did you give the values for the drop down items? It'll be easier if you can post the code.
