Hi

Please see attached screen shots.

I have a UXscrollerview within a listbox/data template.  When I use the top and bottom scoller buttons the text scrolls okay - when I drag the scroller bar I first get a new row on the list box (see screenshot) and then if I keep dragging I get runtime error - can you please advise

I have enclosed XAML
