Add a Load More Button at the end of ListBox without losing Virtualization?

Question

I know by editing the ListBox\'s default style like this, I can have a Button at the very end of the ListBox.

Answer 1

There are a bunch of extra features these days that can help with this scenario. One of them is the addition of additional visual states on the ScrollViewer added "HorizontalCompression" and "VerticalCompression" visual state groups. By making use of these and hooking into the CurrentStateChanging event, you can load more items as you need to.

Full details of how to implement this can be found on the Silverlight for Windows Phone Performance Team Blog.
