I've been Googling and going over docs at MSDN, but I'm sort of stumped on the best way to handle something that I think should be relatively easy...

If I add several radio buttons (lets say colors, "red", "blue", etc) to a GroupBox I should be able to easily get the selected checkbox from this GroupBox, but after looking over all the properties of the GroupBox control, I don't see what to use.

If I can't get it directly from a GroupBox what are the preferred ways to get a handle to the selected checkbox? Loop? Switch? Handle CheckedChange events?

I assume setting the checkbox would be similar (loop or switch).

I was hoping there would be a way to get a direct handle to the selected radio button from the GroupBox.
