Namespace: System.Windows.Controls
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public Orientation Orientation { get; set; }
/** @property */
public Orientation get_Orientation ()

/** @property */
public void set_Orientation (Orientation value)

public function get Orientation () : Orientation

public function set Orientation (value : Orientation)

<object Orientation="Orientation" .../>

Property Value

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

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="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 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>
        </WrapPanel>
  </Border>    
</Page>

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

        
// Create the application's main window
mainWindow = new System.Windows.Window();
mainWindow.Title = "WrapPanel Sample";


// Instantiate a new WrapPanel and set properties
myWrapPanel = new WrapPanel();
myWrapPanel.Background = System.Windows.Media.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 = new Button();
btn1.Content = "Button 1";
btn2 = new Button();
btn2.Content = "Button 2";
btn3 = new Button();
btn3.Content = "Button 3";

// Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1);
myWrapPanel.Children.Add(btn2);
myWrapPanel.Children.Add(btn3);

// Add the WrapPanel to the MainWindow as Content
mainWindow.Content = myWrapPanel;
mainWindow.Show();
