Unfortunately, when there are no items in the list box, you can not scroll to a position where the the header is hidden. It is part of the scrollable content of the list box and when there are no items, the bottom of the header is the bottom of the scrollable content. If you wish to hide the header when there is no data, then you can set the ListHeaderDisplayMode property to "WithDataItems". Finally, I have attached a sample project that demonstrates how you can scroll to the bottom of the list box.
I hope this helps. Please, let us know if you have further questions.
