PerformClick of Button不起作用 [英] PerformClick of Button not work
问题描述
我必须在运行时通过代码触发按钮的click事件.
我无法直接使用btn_click事件，因为在我要触发事件的地方无法访问它.
所以我尝试了PerformClick方法.
它在第一次使用时有效，但在第二次通话时我不做任何事情.
我想我应该在两次调用PerformClick之间做一些事情.
有任何想法吗?
Hi,
I have to fire click event of button by code at runtime.
I cannot drectly use btn_click event because it is not accessible where I want to fire event.
So I try PerformClick method.
it works at first time but I doesbt do anything at second call.
I guess I should do something between two call of PerformClick.
Have any idea?

you can create click event like,
btn_Click += new ButtonClick(callingFunctionName);

我敢打赌，如果您不时停止使用调试器，则可以自行判断发生的情况.
I bet if you stopped to used the debugger once in a while, you could detremine what''s happening on your own.
