title: WinForms: Textbox Leave event doesn't get fired after going to main menu
body: <p>I have a TextBox control on my Form. I use the Leave event on the control to process user input. It works fine if the user clicks on some other control on the form, but the even doesn't get fired when the user goes straight to the main menu. Any ideas which event should I use to get it fired everytime?</p>
