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.

WindowTitle = "WrapPanel Sample"

' Instantiate a new WrapPanel and set properties
Dim myWrapPanel As New WrapPanel()
myWrapPanel.Background = Brushes.Azure
myWrapPanel.Orientation = Orientation.Horizontal

myWrapPanel.Width = 200
myWrapPanel.HorizontalAlignment = Windows.HorizontalAlignment.Left
myWrapPanel.VerticalAlignment = Windows.VerticalAlignment.Top

' Define 3 button elements. The last three buttons are sized at width 
' of 75, so the forth button wraps to the next line.
Dim btn1 As New Button()
btn1.Content = "Button 1"
btn1.Width = 200
Dim btn2 As New Button()
btn2.Content = "Button 2"
btn2.Width = 75
Dim btn3 As New Button()
btn3.Content = "Button 3"
btn3.Width = 75
Dim btn4 As New Button()
btn4.Content = "Button 4"
btn4.Width = 75

' Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1)
myWrapPanel.Children.Add(btn2)
myWrapPanel.Children.Add(btn3)
myWrapPanel.Children.Add(btn4)

' Add the WrapPanel to the Page as Content
Me.Content = myWrapPanel

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