ConfirmButton Server Code

　　先看一段confirm的简介

　　　　ConfirmButton is a simple extender that catches clicks on a button (or any instance of a type derived from Button) and displays a message to the user. If the "OK" button is clicked, the button or link functions normally. If not, the click is trapped and the button will not perform its default submit behavior; optionally, a client script is executed if the OnClientCancel property is set. This is useful for delete links or anything else that requires confirmation from the user.
