Question

如果用户点击它以外的任何地方，我想关闭一个System.Windows.Window。窗口显示为对话框。如何在wpf窗口外收到点击次数？

AppointmentDetailsView.ShowDialog();

Answer 1

这个怎么样？

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    protected override void OnDeactivated(EventArgs e)
    {
        base.OnDeactivated(e);
        Close();
    }
}

经过进一步探索，我找到了一个运作良好的解决方案。希望有人会发现它很有用：

RadWindow PopupWindow;
public SampleView()
{
    InitializeComponent();
    PopupWindow = new RadWindow { Header = "Details", Name = "radWindow" };
    PopupWindow.Loaded += new RoutedEventHandler(PopupWindow_Loaded);
}
void PopupWindow_Loaded(object sender, RoutedEventArgs e)
{
    Canvas canvas = Framework.Traversal.FirstVisualAncestorOfType<Canvas>(PopupWindow);
    canvas.MouseLeftButtonDown -= canvas_MouseLeftButtonDown;
    canvas.MouseLeftButtonDown += canvas_MouseLeftButtonDown;
}
void canvas_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    Point mousepoint = e.GetPosition(null);
    var elements = VisualTreeHelper.FindElementsInHostCoordinates(mousepoint, PopupWindow);
    if (elements.Count() == 0)
        PopupWindow.Close();
}
