推荐答案

1.您应该首先调试代码，然后按在与单选按钮链接的每个事件处理程序中放置断点。然后通过收音机来测试你的表格。

2.如果没有调用你的事件处理程序方法，这意味着你没有错误地将它们与你的控件链接：也许你不小心删除了链接，或者您与其他控件事件链接！

1.You should start by debugging your code, and by putting breakpoints in each event handler that are linked with your radio buttons. Then test your form by clinking on the radio.
2.If your event handler methods are not invoked, this means that you are not linked them incorrectly with your controls: maybe you accidentally delete the links, or you linked with other controls events!
