By using this code you have the gridview row in which the button was clicked.
in the onclick event of your button:

Button btn = (Button)sender;
GridViewRow row = (GridViewRow)btn.NamingContainer;

By using this code you have the gridview row in which the checkbox was clicked.
in the onselectedChanged event of your checkbox:

CheckBox chkbx = (CheckBox)sender;
GridViewRow row = (GridViewRow)chkbx.NamingContainer;
if (chkbx.Checked)
{
 /// your code here to do with the textbox what ever you need to do.

}

I cannot give a more precize answer cause I do not know whether the checkbox or the button shows the value in column 2
