WrapPanel::Orientation Property

Gets or sets a value that specifies the dimension in which child content is arranged.

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

property Orientation Orientation {
	Orientation get ();
	void set (Orientation value);
<object Orientation="Orientation" .../>

Property Value

Type: System.Windows.Controls::Orientation
An Orientation value that represents the physical orientation of content within the WrapPanel as horizontal or vertical. The default value is Horizontal.

Identifier field


Metadata properties set to true


If the Orientation property is set to Horizontal, child content forms horizontal rows first and if necessary forms vertical stacks of rows. If the Orientation property is set to Vertical, child content is first positioned in a vertical column, and if there is not enough space, wrapping occurs and additional columns in the horizontal dimension are added.

The following example demonstrates how to set the Orientation property in Extensible Application Markup Language (XAML).

<Page xmlns="" WindowTitle="WrapPanel Properties Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Orientation="Horizontal" Background="Azure" ItemWidth="25" ItemHeight="25" Height="200" Width="200">
            <Button Width="200">Button 1</Button>
            <Button>Button 2</Button>
            <Button>Button 3</Button>

The following example demonstrates how to set the Orientation property by using code.

         // Create the application's main window
         mainWindow = gcnew System::Windows::Window();
         mainWindow->Title = "WrapPanel Sample";

         // Instantiate a new WrapPanel and set properties
         myWrapPanel = gcnew WrapPanel();
         myWrapPanel->Background = Brushes::Azure;
         myWrapPanel->Orientation = Orientation::Horizontal;
         myWrapPanel->ItemHeight = 25;

         myWrapPanel->ItemWidth = 75;
         myWrapPanel->Width = 150;
         myWrapPanel->HorizontalAlignment = HorizontalAlignment::Left;
         myWrapPanel->VerticalAlignment = VerticalAlignment::Top;

         // Define 3 button elements. Each button is sized at width of 75, so the third button wraps to the next line.
         btn1 = gcnew Button();
         btn1->Content = "Button 1";
         btn2 = gcnew Button();
         btn2->Content = "Button 2";
         btn3 = gcnew Button();
         btn3->Content = "Button 3";

         // Add the buttons to the parent WrapPanel using the Children.Add method.

         // Add the WrapPanel to the MainWindow as Content
         mainWindow->Content = myWrapPanel;

<Page xmlns="" WindowTitle="WrapPanel Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Background="LightBlue" Width="200" Height="100">
            <Button Width="200">Button 1</Button>
            <Button>Button 2</Button>
            <Button>Button 3</Button>
            <Button>Button 4</Button>
