WrapPanel.ItemHeight Property
Gets or sets a value that specifies the height of all items that are contained within a WrapPanel.
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
<object ItemHeight="double"/> - or - <object ItemHeight="qualifiedDouble"/> - or - <object ItemHeight="Auto"/>
XAML Values
Property Value
Type: System.DoubleThe Double that represents the uniform height of all items that are contained within the WrapPanel. The default value is NaN.
If this property is not set (or if it is set to Auto in XAML or to Double.NaN in code), the size of the layout partition is equal to the desired size of the child element.
A child element of a WrapPanel may have its height property set explicitly. ItemHeight specifies the size of the layout partition that is reserved by the WrapPanel for the child element. As a result, ItemHeight takes precedence over an element's own height.
The following example demonstrates how to set the ItemHeight 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 ItemHeight 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.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.Content = "Button 2";
btn2.Width = 75;
btn3 = new Button();
btn3.Content = "Button 3";
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
mainWindow.Content = myWrapPanel;
mainWindow.Show();
