如果点击其他任何地方,Windows Phone关闭弹出窗口

Question

我有一个我正在开发的Windows Phone应用程序,我的共享按钮打开一个带有几个选项的小弹出窗口,使用以下代码:

       private void share_Click(object sender, System.EventArgs e) 
    {

        Popup share= new Popup();
        share.Child = new sharePopup();
        share.IsOpen = true;
        share.VerticalOffset = 30;
        share.HorizontalOffset = 0;
    }

现在,这个弹出窗口有一个"关闭"按钮,但是如果我不点击它,而是点击前一个仍然可见的页面上的另一个按钮,即使在移动到新页面之后,弹出窗口也会保持原位.我必须点击"关闭"弹出窗口才能消失.

如果我点击弹出窗口之外的任何地方,我正在寻找的方法是关闭弹出窗口.是否有预定义的方法来执行此操作？如果没有,我可以采取哪些方式？

提前致谢

编辑:这是弹出窗口的c#代码

      public partial class sharePopup : UserControl
{
    public sharePopup()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {            
        Popup mensaje = this.Parent as Popup;
        mensaje.IsOpen = false;
    }
      private void UserControl_Loaded(object sender, RoutedEventArgs e)
    {
        this.Focus();
    }

    private void UserControl_LostFocus(object sender, RoutedEventArgs e)
    {
        Popup mensaje = this.Parent as Popup;
        mensaje.IsOpen = false;
    }
}

}

弹出窗口的XAML仅包含大小,颜色和按钮定义:

IsLightDismissEnabled="True"当你宣布你的Popup控制时,我发现有用的设置. MSDN描述
