Hi,
it seems that StackVirtualizationStrategyDefinition does not work.
My scenario, used in my app for Windows Phone 8, is to load new tweets and then put them one after one from the top by doing insert(0, tweet).
In Windows Phone UI I was able to set in XAML inside the RadDataBoundList control:
<Primitives:RadDataBoundListBox.VirtualizationStrategyDefinition>
<Primitives:StackVirtualizationStrategyDefinition Orientation="Vertical" ReorderMode="MoveItemsUp"/>
</Primitives:RadDataBoundListBox.VirtualizationStrategyDefinition>
That lets me to insert (0, tweet) in itemssource without losing focus of list position. This is a *very great behavior and feature* . Moreover if I want to add tweets after the last item in itemssource (as usual) I just change ReorderMode="MoveItemsDown" and list does not lose position again!! :)
Unfortunately this behavior does not work anymore. It seems that it's just ignored . May be you didn't implement it yet.
Best Regards
Alessandro
