现在，从这里开始阅读，看看如何使用OnCheckedChanged event:

MSDN:RadioButton类 [

Good go ahead and implement it.

It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it''s not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
