将命令绑定到窗口标题栏的 X 按钮
我的 WPF 维护窗口有一个带有“退出”按钮的工具栏; CommandExit 与此按钮绑定。 CommandExit 在退出前执行一些检查。
现在,如果我单击窗口的关闭按钮(标题栏的 x 按钮),则会忽略此检查。
如何将 CommandExit 绑定到窗口 x 按钮?
My WPF maintenance window have a toolbar with a button "Exit"; a CommandExit is bind with this button. The CommandExit perform some checks before exit.
Now, if I click to close button of the window (x-button of title bar), this checks are ignored.
How can I do to bind CommandExit to window x-button?

我想您可能想根据这些条件取消关闭?您需要使用关闭事件,它会向您传递一个 System.ComponentModel.CancelEventArgs 来取消关闭。
您可以在代码隐藏中挂钩此事件并手动执行命令,或者,这将是首选方法,您可以使用附加行为来挂钩事件并触发命令。
类似的东西(我还没有测试过):
I assume you may want to cancel closing based on these conditions? You need to use the Closing event, which passes you a System.ComponentModel.CancelEventArgs to cancel the close.
You can either hook this event in code-behind and execute the command manually, or, and this would be the preferred approach, you could use an attached behavior to hook the event and fire the command.
Something along the lines of (and I haven't tested this) :
您必须实现主窗口事件“Closing”的事件处理程序,您可以在其中进行检查并取消关闭操作。这是最简单的方法,但是否则您必须重新设计整个窗口及其主题。
You have to implement event handler of your main window's event "Closing" where you can do checks and cancel the closing action. This is easiest way to do it, however otherwise you have to redesign whole window and its theme.
