使用键盘快捷键控制丢失焦点事件

For both .NET Winforms and Windows Presentation Foundation, if I have a text box that the user has just entered text into, and a button, if the user clicks the button the "LostFocus" event fires before the button click event fires. However if the user uses a keyboard shortcut for the button (e.g. Button's text is "&Button" or "_Button" and user performs Alt+B), then the "LostFocus" event fires after the button click event, which is less useful.For both .NET Winforms and Windows Presentation
