Regarding the issue of lazy loading：When using itemscontrol, listview, and listbox to implement dynamic data loading, there may be limitations with scrollbars.

When using itemscontrol, listview, and listbox to implement dynamic data loading, there may be limitations with scrollbars.

The specific situation is that when the data volume is 1 million, 100 records need to be displayed each time. So when the user browses through 90 records, they need to add 50 records and delete the previous records to keep the loaded records at 100. At this time, the scrollbar will reach the bottom and cannot trigger a new load.
May I ask if it is possible to open up the ScrollContentViewer? I would like to customize a scrollbar that allows for infinite scrolling. Thank you for reading.
