Property Value

Type: System.Windows.Controls.ItemsPanelTemplate
An ItemsPanelTemplate that defines the panel to use for the layout of the items. The default value for the ItemsControl is an ItemsPanelTemplate that specifies a StackPanel.

Dependency property identifier field: ItemsPanelProperty

To affect the layout of the items in an ItemsControl, you use this property to specify a ItemsPanelTemplate.

The following example creates a ListBox that displays items horizontally. The example sets the ItemsPanel to an ItemsPanelTemplate that has a StackPanel whose Orientation property is set to Horizontal. For this example, src is defined as xmlns:src="clr-namespace:ItemsControlSnippets".

    <Style x:Key="horizontalListBoxStyle" TargetType="ListBox">
      <Setter Property="ItemsPanel">
            <StackPanel Orientation="Horizontal"

    <src:Items x:Key="items"/>

  <ListBox ItemsSource="{StaticResource items}" 
           Style="{StaticResource horizontalListBoxStyle}"/>


The following example shows the collection of strings that the ListBox is bound to.

Public Class Items
    Inherits System.Collections.ObjectModel.ObservableCollection(Of String)

    Public Sub New()
        Add("Item 1")
        Add("Item 2")
        Add("Item 3")
        Add("Item 4")
        Add("Item 5")
    End Sub
End Class

The previous example produces output that resembles the following illustration.
