check into some of the new properties in the button control ('OnCommand',
'CommandName', and 'CommandArgument'). 'OnCommand' is used in place of the
'OnClick' property. Then, we can use any combination of 'CommandName' and
'CommandArgument' in the shared subroutine (or event handler), to process
the event.
