Property Value

Type: System.Windows.Controls.VirtualizationMode
One of the VirtualizationMode values.

Remarks

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.
