UI virtualization for WPF

Many times, our interface presents a large amount of data, such as a table with thousands of records or an album with hundreds of photos. 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 scenario--ui
