Jerry why don't you add the PK field into the grid and put the visible property of the column to false, that's what I always do.

I like the SelectedIndexChanged event because of the SelectedValue property, but that would mean all four buttons need the "CommandName" property set to "SELECT". This gives me the primary key value in SelectedValue but then I can't tell which button the user pressed.

>>>I have a webform with a gridview that has 4 columns. Two of the columns are "ButtonField". One button is for Edit, one is button is for Delete. Both buttons's "CommandName" contains "SELECT". The SelectedIndexChanged of the grid points to "MyMethod()".
>>>
>>>When I run the form and click on either button, "MyMethod()" gets control, but how can I tell which button was pressed, the Edit or the Delete?
