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 to improve ListView 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 the EnableVirtualizationopens in a new tab API in Listview.
