How to unselect a row in gridview control?

Hi, I'm using vs2013, web form and c#
I have a datagrid control that I bound to a database table.  In Design view, I selected the smart tag and added a Select button.  It's showing up and selecting the row.  However, once selected, there is no Cancel button.  How can I unselect a row?
Thank you.

Typically selecting another row will unselect the previous selection.

I will assume that you have a CommandField with ShowSelectButton = true, so I would think that you would just need to set ShowCancelButton = true.
