ASP.NET Gridview

We used the method Controls [index] because the CommandField columns doesn’t have an ID for us to use FindControl method. In addition we cannot even set an ID to a CommandField column.

We also passed the value of 6 in the cells index. This means that the ShowDeleteButton link is located at the 7th column of the GridView (You need to change the index value based on your gridview column declaration), by default cells index starts at 0.

<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />

if you are declaring the buttons like in the above declaration. Then we need passed the value of 2 in the Controls index in order to get reference to the ShowDeleteButton link.

That should work. One more thing, if you want to really customize the controls within GridView, then I would really recommend you use TemplateFields instead.
