I'm a complete newbie to C# and .Net programming, and am just learning the
environment by rewriting one of my existing Delphi apps from the ground up
in C# 2008 Express.

I've got a row of buttons which I want to work like radio buttons - that is,
one of the buttons in the row is "down", and clicking on another button
makes that one "down" and the previous one "up".

Obviously I could use radio buttons for this, but they look so ugly in
modern applications.  Delphi offers a TSpeedButton, which has a property
called "GroupIndex".  By setting several buttons to the same GroupIndex they
work just like radio buttons, but with the more pleasing appearance of a
normal button.

It must be possible to do this in Visual Studio - I'm sure I must be missing
something really obvious.  If anyone could help I'd really appreciate it.
