推荐答案

容易，很容易实现，但这不是一个好主意.例如，它将使鼠标无法访问该按钮，并使您的用户疯狂.

可以使用方法Control.OnLostFocus和Control.OnGotFocus的重载或事件LostFocus和GotFocus来实现.

Easy, very easy to implement, but this is a bad idea. For example, it will make the button not accessible by mouse and will drive your user crazy.

The implementation can be done using overloaded of the methods Control.OnLostFocus and Control.OnGotFocus or using the events LostFocus and GotFocus.

我想这很接近:
带有浏览按钮的文件搜索器编辑控件 [

I guess this one is pretty close:
File Searcher Edit Control with Browse Button[^] - just modify to suit your needs.
