I am using the ZapPanel in a listbox, pretty much following the example. When the user clicks a button to add an item, that item is added to the end of the list, and may be over to the right some distance, requiring the user to scroll for a while to get to it. (You can see the same thing in the sample, although it's vertically oriented, but you can add items for a while, and it will be necessary to manually scroll down to see them).
I'd like to smoothly scroll over to right until that last item is the selected item. I can just simply set the listbox's selected item, but then when it becomes the selected item, everything else fades in on the left hand side, and it's not a very good visual effect (in my opinion).
I tried calling LineRight() on the ScrollViewer as many times as necessary, but this did not result what I was looking for.
Any suggestions?
