Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem...

You need to include Template Field for every column you want to provide Editing because Template Field provides you both Item Template and Edit Item Template to create interface for two separate Grid View modes. You need to handle Grid View events such as Row Editing, Row Canceling Edit and Row Updating to provide desired editing functionality.Font-Names="Verdana" Font-Size="10" Data Key Names="Product ID" Auto Generate Columns="false" onrowcancelingedit="Grid View1_Row Canceling Edit" onrowediting="Grid View1_Row Editing" onrowupdating="Grid View1_Row Updating"In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.
