I have three radio buttons in a group on a form.

I bind these to three boolean properties of a business object.This binding 
changes the behavior of the buttons.

Let's say button1 is selected. When I click one time on button2, then 
button1 is unselected. I then must click a second time on button2 before is 
shows as selected. Note that one click is sufficent when there is no binding 
in place.

I can change the behavior by changing the DataSourceUpdateMode to 
"OnValidation." However, for other reasons on the form, I need to have this 
set to "OnPropertyChange."

I see this as an error. Any advice on getting around this would be 
appreciated.

Thanks,
Steve

I implemented a hack to solve this. In the MouseDown event I set 'Checked' 
to true. Pretty silly but it seems to work in preliminary testing. However, 
it violates a principle I am trying to live by where there is as close to 
zero code in the UI as possible. I still think this is bug.
