GridView edit mode Edit/Delete link become button - how?


The standard Gridview edit mode provides "Edit" and "Delete" hyperlink (called linked button) for us to click and update record.
How to make them buttons instead of hyperlik ?
I could not find the codes for these 2 default hyperlinks to modify.
Thanks

I found the solution. We can edit column and then change from link to button.
