The following example demonstrates how to set the ItemWidth 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>

The following example demonstrates how to set the ItemWidth 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.
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();
// 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.Width = 200;
myWrapPanel.HorizontalAlignment = HorizontalAlignment.Left;
myWrapPanel.VerticalAlignment = 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.
btn1 = new Button();
btn1.Content = "Button 1";
btn1.Width = 200;
btn2 = new Button();

btn2.Width = 75;
btn3 = new Button();

btn3.Width = 75;
btn4 = 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 MainWindow as Content

If this property is not set (or if it is set to Auto
in Extensible Application Markup Language (XAML) or to Double.NaN
in code), the size of the layout partition is equal to the DesiredSize of the child element.
A child element of a WrapPanel may have its width property set explicitly. ItemWidth specifies the size of the layout partition that is reserved by the WrapPanel for the child element. As a result, ItemWidth takes precedence over an element's own width.
