add event handler to dynamically created button

Does anyone have a good vb example of adding an "onClick" event to a button that is dynamically added into a templatefield of a gridview.  MSDN just says to use the addhandler statement with no other good info for a 'dynamic' scenario:

Thanks in advance for any advice.
