Programming FAQ record: events with clearly responded buttons, but cannot be captured by programs

For example, I wrote a private void button#click (Object sender, system. eventargs E)
There is a corresponding process for processing data in it. During debugging, we often set breakpoints in it and monitor its variables. Occasionally, this problem occurs when the button#click process is clearly found during debugging, but the breakpoint I set is not captured. Then the problem is found in # region web form designer generated code. You need to check whether private void initializecomponent () has this process. If this problem occurs, there is no such problem. How can we let him out? You can go to the design page and double-click the button again to let him enter this method, this method is automatically registered in private void initializecomponent.
I think this problem may not be taken into account by Microsoft when simulating the event-driven model. In short, writing BS is a headache, and there are far more problems than CS.
