Question

我观察到当Popup控件失去焦点时，它会将焦点返回到启动Popup的对象。所以基本上是这一系列的事件。

Textbox GotFocus触发，我打开弹出窗口
完成Popup用户点击Popup外的任何地方以激活LostFocus
LostFocus激活，但在步骤1（文本框）中的对象的GotFocus执行后立即执行 - 重新启动弹出窗口。

我的问题是，有没有办法将焦点重置为首次启动应用时的默认值？我想阻止它将焦点返回到启动弹出窗口的控件。

编辑：我删除了LostFocus事件，因为我发现没有必要在用户点击时从视图中删除弹出窗口。

    Popup p;
    public MainPage()
    {

        this.InitializeComponent();

        this.NavigationCacheMode = NavigationCacheMode.Required;
        p = new Popup();
        p.IsLightDismissEnabled = true;
        //p.LostFocus += p_LostFocus;

    }


    private void m_GotFocus(object sender, RoutedEventArgs e)
    {
        if (p.IsOpen != true)
        {
            // Create some content to show in the popup. Typically you would 
            // create a user control.
            Border border = new Border();
            border.BorderBrush = new SolidColorBrush(Colors.Black);
            border.BorderThickness = new Thickness(0);

            StackPanel panel1 = new StackPanel();
            panel1.FlowDirection = Windows.UI.Xaml.FlowDirection.LeftToRight;
            panel1.Background = new SolidColorBrush(Color.FromArgb(255, 30, 30, 30));

            Button button1 = new Button();
            button1.Content = ".";
            button1.Margin = new Thickness(5.0);
            button1.BorderThickness = new Thickness(0);
            button1.Background = new SolidColorBrush(Color.FromArgb(255, 90, 90, 90));
            button1.Click += new RoutedEventHandler(Feedback_Click);

            TextBlock textblock1 = new TextBlock();
            textblock1.Text = "";
            textblock1.TextWrapping = TextWrapping.WrapWholeWords;
            textblock1.Margin = new Thickness(5.0);
            panel1.Children.Add(textblock1);
            panel1.Children.Add(button1);

            border.Child = panel1;

            // Set the Child property of Popup to the border 
            // which contains a stackpanel, textblock and button.
            p.Child = border;

            // Set where the popup will show up on the screen.
            p.VerticalOffset = 400;
            p.HorizontalOffset = 100;

            // Open the popup.
            p.IsOpen = true;
        }

    }

在Popup LostFocus之后将焦点重置为默认值
