I have a lot of items to display in a LongListSelector (around 8000). I want to partially load items (and eventually also dispose items when they are out of the visible view). I know also the content of the jump list. At initialisation I load 20 items. While the user scrolls down, I load more items (implemented the ItemsRealized event). Now when the JumpList is closed, I want to know which item of the jump list is selected in order to build the list before and after the jump position.
How do I know the selected jump item after the jump list is closed?
