I was just about writing you that we can consider implementing this in a future release but have mistakenly sent you my answer unfinished.
You can also implement this behavior now as well by writing some code which iterates over all containers realized in the list box upon navigating to the container page and playing a Storyboard that translates the elements as you require.
The RadDataBoundListBox control exposes the RealizedContainers
property that returns all visual containers currently displayed in the control. You can simply traverse the element tree of each container, find the elements you would like to animate and play a storyboard on them. This should happen each time you navigate to a page or a pivot item.
Let me know if you have further questions.
