override grouping of radiobuttons

I want to make a custom control that extends radiobutton and allows me to specify the grouping, so does anyone know how radiobutton groupings work at a low level? This is in windows forms btw

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

From what I can determine, your best bet to create your own grouping with radio buttons would be to extend checkboxes or button base.  Basically what you'd want to do is reference back to parent, and check for other instances of your control within the same group and uncheck them when a particular instance is checked.

There may be a method of the radio button control that you could override to provide this same functionality, but i don't see anything obvious.

Good luck...
