SfListView allows you to load more items at the top of the list automatically when reaching the Header item by using the property. Show the busy indicator until the items are added into the collection as like below code example.
Insert each new item in the zeroth position of the underlying collection which is bound to the property. When the collection gets modified, the ScrollViewer scrolls to the top of the list. Using method scroll back to the previous item index as like below.
