Description

Standard Layout systems can create item containers and calculate layouts for each item associated with a list control.   If multiple UI elements are generated when only a few elements appear on the screen, the performance of the application can be negatively impacted.  

For example,VirtualizingStackPanel calculates the number of visible items and processes from ItemsControl (such as a ListBox or ListView) ItemContainerGenerator to create UI elements for visible items only.
