Popup 类的用法

// Create the popup object.
Popup p = new Popup();
privatevoid showPopup_Click(object sender, RoutedEventArgs e)
{
    // 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(5.0);

    StackPanel panel1 = new StackPanel();
    panel1.Background = new SolidColorBrush(Colors.LightGray);

    Button button1 = new Button();
    button1.Content = "Close";
    button1.Margin = new Thickness(5.0);
    button1.Click += new RoutedEventHandler(button1_Click);
    TextBlock textblock1 = new TextBlock();
    textblock1.Text = "The popup control";
    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 = 25;
    p.HorizontalOffset = 25;

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

}

void button1_Click(object sender, RoutedEventArgs e)
{
    // Close the popup.
    p.IsOpen = false;

}
