Some time ago we talked about it. If you wanna clear all radiobuttons there's 
an easy workaround. Add a radiobutton (say HiddenRadioButton)  in the group 
and set its "Visible" property FALSE.

So when you want to clear radiobuttons, just select the hidden radiobutton, 
HiddenRadioButton.Value = TRUE and all others in the group will be cleared.

Ciao,

Stefano
