c# - How to animate Silverlight 4 ListBox items when the bound data is sorted? -


i'm trying find out happens when data bound itemssource changes. method should override able make items animate new positions in sorted list?

from found out far might have hijack layoutupdated of scrollviewer inside listbox? how find out happens there in order able attach animation listboxitems' position assignments?

actually nicer attached triggers , behaviors , not having extend listbox class.

edit: turned out both pagedcollectionview , collectionviewsource destroys , recreates item list on sorting, rearranging list animation doesn't seem possible without either implementing sorting manually moving existing items around in list or create sort of item buffer, both of sounding possible source of weird bugs , performance bottleneck. if has working solution these though i'd glad pointers!
