Ken,

>>Windows Forms Radio buttons are odd animals...you would expect the behavior you mentioned above, but that's not how they work. They are more a "loose confederation" of individual controls rather than acting as a single control. You can't data drive the selection, because there is not a single value that represents the selection. Each radio button in a group has its own Checked property which is either true or false.

I had to choose whether to data bind the control at all or not, but decided it best to provide at least some type of data binding...thus the text of each radio button can be data driven.

Regards,
