By default, a VirtualizingPanel creates an item container for each visible item and discards it when it is no longer needed (such as when the item is scrolled out of view). When an ItemsControl contains a lot of items, the process of creating and discarding item containers can negatively affect performance. When is set to Recycling, the VirtualizingPanel reuses item containers instead of creating a new one each time.
The following example shows the data used in the previous example.
