Remarks
When an IXRItemsControl contains many items, the process of creating and discarding item containers can negatively affect performance. Virtualization refers to a technique by which a subset of UI elements are generated from a larger number of data items based on which items are visible on the screen. Through functionality that is provided by IXRVirtualizingPanel, IXRVirtualizingStackPanel calculates visible items and works with an internal implementation of the ItemContainerGenerator from an IXRItemsControl (such as IXRListBox) to create UI elements only for visible items.
