The ItemsPanelTemplate specifies the panel that is used for the layout of items. The ItemsControl has an ItemsPanel property that is of type ItemsPanelTemplate.

The following example creates a ListBox that displays its items horizontally. The example sets the ItemsPanel to a ItemsPanelTemplate that has a StackPanel whose Orientation property is set to Horizontal.


<Grid>
  <Grid.Resources>
    <Style x:Key="horizontalListBoxStyle" TargetType="ListBox">
      <Setter Property="ItemsPanel">
        <Setter.Value>
          <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"
              VerticalAlignment="Center"
              HorizontalAlignment="Center"/>
          </ItemsPanelTemplate>
        </Setter.Value>
      </Setter>
    </Style>

    <src:Items x:Key="items"/>
  </Grid.Resources>

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

</Grid>


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


public class Items : 
    System.Collections.ObjectModel.ObservableCollection<string>
{
    public Items()
    {
        Add("Item 1");
        Add("Item 2");
        Add("Item 3");
        Add("Item 4");
        Add("Item 5");
    }
}


The preceding example produces output that is similar to the following illustration.
