Popup.HorizontalOffset Property

Gets or sets the distance between the left side of the Silverlight control and the left side of the popup. 

Namespace:  System.Windows.Controls.Primitives
Assembly:  System.Windows (in System.Windows.dll)

public double HorizontalOffset { get; set; }
<Popup HorizontalOffset="double"/>

Property Value

Type: System.Double
The distance, in pixels, between the left side of the Silverlight control and the left side of the popup.

Dependency property identifier field: HorizontalOffsetProperty

By default, the popup displays in the upper-left corner of the Silverlight content. You can change this positioning by setting the HorizontalOffset and VerticalOffset properties.

The following example shows how to use the VerticalOffset and HorizontalOffset properties to determine where the popup displays on the Silverlight control. The popup content is created inline for conciseness, but you would typically create this content in a separate user control and use an instance of that control as the child of the popup.


// Create the popup object.
Popup p = new Popup();
private void 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;

}
