     <ListBox Name="lsTest">

            <ListBox.ItemsPanel>

                <ItemsPanelTemplate>

                    <VirtualizingStackPanel Orientation="Horizontal" />

                </ItemsPanelTemplate>

            </ListBox.ItemsPanel>

            <ListBoxItem>Item1</ListBoxItem>

            <ListBoxItem>Item2</ListBoxItem>

            <ListBoxItem>Item3</ListBoxItem>

     </ListBox>

与以下代码效果相同：

FrameworkElementFactory panelFactory = new FrameworkElementFactory

                (typeof(VirtualizingStackPanel));

            panelFactory.SetValue(VirtualizingStackPanel.OrientationProperty, Orientation.Horizontal);

 

            this.lsTest.ItemsPanel = new ItemsPanelTemplate(panelFactory);
