I've seen a lot of questions that ask how to set a scroll position, however I don't need to set the position, I need to get it. For the Windows Universal application I'm writing I need to check if the user scrolled all the way up. If the user has scrolled all the way up I need to make a request to my server to get more data to show to the user.
How do I see the scroll position of a listbox in code? Is there some kind of value changed event or something that I can use?
