I have 2 sets of radio buttons  where value choosen in 1 set is  dependent
on the other set.

In buttonselectionchanged  event I have the code to throw an exception if value choosen is wrong and then in catch handler I show that message. But its getting called 2-3 times...showing message box 2-3 times...

How can we avoid  this....

Try hooking up the rb1, rb2 and rb3 "Click" event and not selection changed.
