Hi Fei,

Thanks for writing.

As of Q3 2011 Mango we have migrated our RadDataBoundListBox to internally use the scrolling logic provided by the native ScrollViewer. Since in Windows Phone Mango this control has been greatly optimized for smoother user experience by handling the input on a new, separate thread and performing the scrolling there, we decided to uprage our control so that we make use of this optimization. This, however, implied some breaking changes which we listed in our release notes and loosing some of the scrolling states previously available was one of the breaking changes.

Since, however, Microsoft have announced that they will extend the visual states exposed by the ScrollViewer with further, "compression" states (actually this will happen when the user reaches the end of the scrolling area and simply stretches the content) we can map our Top-&BottomStretch states to them and re-enable them. This will happen after Microsoft officially release their development tools targeting the Mango platform.

I hope this answers your question.

Greetings,
Deyan
