Remarks

In this context, "virtualize" refers to a technique by which a subset of user interface (UI) elements are generated from a larger number of data items based on which items are visible on the screen. It is intensive, both in terms of memory and processor, to generate a large number of UI elements when only a few may be on the screen at a given time. A panel that inherits from VirtualizingPanel, such as the VirtualizingStackPanel, calculates visible items and works with the ItemContainerGenerator from an ItemsControl (such as ListBox or ListView) to only create UI elements for visible items.

The following lists describes cases when the VirtualizingPanel cannot virtualize item containers:

  • The ItemsControl contains item containers of different types. For example, a Menu might have items that use both MenuItem and Separator objects as the item containers.

  • You explicitly create the item containers to the ItemsControl. For more information about explicitly versus implicitly creating item containers, see the ItemsControl class.

When a VirtualizingPanel is virtualizing item containers, you may need to save state information that is associated with a container instead of with the data item itself. For example, if an item is contained by an Expander control, the state is bound to the item container, and not to the data item itself. When the Expander is reused for a new item, the current value of is used for the new item. In addition, the old item does not retain its value.

Examples

The following example demonstrates how to use the derived VirtualizingStackPanel class in Extensible Application Markup Language (XAML).

<StackPanel DataContext="{Binding Source={StaticResource Leagues}}">
    <TextBlock Text="{Binding XPath=@name}" FontFamily="Arial" FontSize="18" Foreground="Black"/>
        <ListBox VirtualizingStackPanel.IsVirtualizing="True" 
                 ItemsSource="{Binding XPath=Team}" 
                 ItemTemplate="{DynamicResource NameDataStyle}"/>      
</StackPanel>
