Radio button group event?

I have a control with several radio buttons used to choose a column
delimiter for text files.  If I want to raise a DelimiterChanged event from
my control, I have to attach an event handler to the CheckChanged event of
each constituent radio button.  Is there another way of doing this?  Say I
wanted to add ten more explicit delimiter choices, I wouldn't like to have
to code ten more delegate assignments, as little work as it is.
