Why? Do you think that you have to write 50 lines of code for that? :-)

Of course, add the handler of the event CheckedChanged to all radio buttons. You need only one line of code to do this; and it should be only one method for all those radio buttons. Don't even play with the idea of doing it through designer, do it in code. Designer is for manual work, slow and unreliable, code is for writing real abstraction and reuse. Also, you should not write a switch of 50+ cases. Put all data it Tag of each instance of the control and use it to avoid checking what instance is it.

That said, you should not even use the designer for add 50+ controls. Is such cases, always do it in code, and get strings (texts for the control) from some data file which you can embed in the application as a .resx resource. Only in this case you can add an event handler(s) to each one in one line (loop). What, VB.NET? Sorry, some three-five lines no matter how many radio boxed do you use.

By the way, 50+ radio boxes is already too many for good UI design. Use something like just one ListBox instead; this will be even easier. And you will need only one instance of event and event handler. Win! :-)
