Description

UI virtualization is an optimization technique to avoid unnecessarily constructing and rendering objects for list items by loading only visible list items in a view port. This helps improve list view performance when loading a large number of items. The list items are updated dynamically while users scroll the list. The virtualization can be enabled by using enablevirtualization API in Listview.
