即使我从菜单中打开新屏幕，WPF Popup也不会关闭

Question

我在Usercontrol中有一个WPf弹出窗口我打开＆amp;通过绑定IsOpen属性关闭。我面临的问题是，即使我使用热键从菜单打开一个新屏幕并且它显示在新屏幕的顶部，弹出窗口也不会关闭。我试图设置StaysOpen =“False”但它不起作用。

Popup IsOpen =“{Binding RelativeSource = {RelativeSource TemplatedParent}，Path = IsPopupOpen，Mode = OneWay，UpdateSourceTrigger = PropertyChanged}”                                Horizo​​ntalAlignment =“Center”VerticalAlignment =“Center”PopupAnimation =“Fade”Horizo​​ntalOffset =“30”StaysOpen =“False”＆gt;

谢谢，
