Thanks for writing.
I am not quite sure that I correctly understand your point here. In our latest version of RadDataBoundListBox
we plug into the native ScrollViewer
and thus use its support for off-thread scrolling which makes the scrolling experience as smooth as possible. If your note here targets the frequency in which the Scrollbar
is updated - yes, this is not as smooth as in the standard ListBox
control because in the standard control the scrollbar is also updated off-thread (on the newly introduced Manipulation thread
This is possible only in case the entire scrolling logic is implemented by inheriting from the ScrollViewer
's interfaces which - currently - are internal and thus not accessible for third party developers. In general, this is not an issue, but a limitation that with the current Windows Phone 7 API we are not able to overcome. We still believe though that having the smooth and responsive scrolling experience, a faster UI virtualization engine and a bigger feature set make RadDataBoundListBox
a great alternative over the standard one.
Do not hesitate to get back to us in case you have further questions or feedback to share.
All the best,
