Msgbox on validation appears many times

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....

This method is called on selection changed event of rb1,rb2,rb3 etc...

Similarly with combobox...

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