This blog will cover virtualization technologies in WPF.1. Data virtualization Typically, we say that virtualization means that the data source is not fully loaded, loading only the data that is currently needed for display to the user. This scenario reminds us of the data paging display, which requests the data based on the number of pages when the data for a particular page is needed.WPF did not provide support for the data virtualization primitive

Because rendering the UI is a relatively expensive action, rendering hundreds of photos at once is a lot of memory and time for the current computer performance. Therefore, it needs to be optimized. Most of the previous scenarios were page-flipping, which caused a disruption to users ' browsing in some way, so a new
