If you are using command buttons, then do not use Auto Generate Edit Button. A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.I put a breakpoint on the Row Updating event handler and found that the event is not fired.

Right now, I have not written code for the Update event. Then the page posts back, the text boxes go back to being labels and the new values are lost, and the Row Updating code never fires.Many a times in our applications we use primary keys to get control of the particular record in the gridview.

For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.

Secondly if you want to include a custom field (some button or link) in the same column it’s not possible.

If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.

In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.

May be you may think why am I using link buttons as we are provided with some command field buttons by Grid View.

We can achieve the same functionality using Datakeys.
