VirtualizingStackPanel.VirtualizationMode Attached Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets or sets how a panel in an ItemsControl virtualizes its child items.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
By default, a VirtualizingStackPanel 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 the VirtualizationMode attached property is set to Recycling, the VirtualizingStackPanel reuses item containers instead of creating a new one each time.
When VirtualizingStackPanel cannot recycle item containers, it uses the standard mode of virtualization, which is to create and discard item containers for each item.
