    using Windows.UI.ApplicationSettings;

            double _settingsWidth = 364;
            Popup _settingsPopup;

                    await Windows.System.Launcher.LaunchUriAsync(helpURL);

                    Window.Current.Activated += OnWindowActivated;
                    _settingsPopup.IsLightDismissEnabled = true;
                    _settingsPopup.Width = _settingsWidth;
                    _settingsPopup.Height = _windowBounds.Height;
    
                    SettingsPage sp = new SettingsPage();
                    sp.Width = _settingsWidth;
                    sp.Height = _windowBounds.Height;
    
                    _settingsPopup.Child = sp;
                    _settingsPopup.SetValue(Canvas.LeftProperty, _windowBounds.Width - _settingsWidth);
                    _settingsPopup.SetValue(Canvas.TopProperty, 0);
                    _settingsPopup.IsOpen = true;
                });
                args.Request.ApplicationCommands.Add(cmd);
            }
    
          
            void _settingsPopup_Closed(object sender, object e)
            {
                Window.Current.Activated -= OnWindowActivated;
            }
            void OnWindowActivated(object sender, Windows.UI.Core.WindowActivatedEventArgs e)
            {
                if (e.WindowActivationState == Windows.UI.Core.CoreWindowActivationState.Deactivated)
                {
                    _settingsPopup.IsOpen = false;
                }
            }

    在SettingsPage中:

    using Windows.UI.ApplicationSettings;
    
               private void btgoBack_Click_1(object sender, RoutedEventArgs e)
            {
                if (this.Parent.GetType() == typeof(Popup))
                {
                    ((Popup)this.Parent).IsOpen = false;
                    SettingsPane.Show();
                }
    
            }
