In my original post I showed how I am doing this in a ListView and it has been working perfectly. I am confused as to why the GridView control cannot do the exact same thing. The ListView is inside an UpdatePanel as is the GridView. The ListView checkbox has AutoPostback="true" and it runs the event and does exactly what I want and it gets the datakey value that I need to do my processing. Please let me know what is different between the 2 controls that I can't do the exact same thing. Thanks. David

Thanks. > Maybe, it's due to the Listview has item events and the gridview has row events that you can get away with it on a Listview what you did. I don't know. I forgot what I was doing when the expert sat down with me doing a hidden field thing on an item within the ItemTemplete to get some other information I needed, but I could not get to it by any other means using a RadListView. It's in the hidden field example that used the Eval in the link. I do remember on an HTML <TD onClick> that it called a javascript function. <TD>'s were present in the Itemtemplete of a RadListView. <TD> <asp:control /> </TD> <http://weblogs.asp.net/aghausman/archive/2009/01/08/get-primary-key-on-row-command-gridview.aspx
