I was having serious performance problems on a ListBox, and after I applied your solution, it worked very well, the performance is great now. I had to modify your VirtualizedCollection to support insertions and deletions from the list. I saw Per solution (in the first post of the series), but it did not help me. So I did a solution where the VirtualizedCollection implements INotifyCollectionChanged and I trigger the CollectionChanged event only for Add and Remove (the Reset event of the AsyncVirtualizedCollection has a awful behavior ...). It worked very well. Thanks for all your effort on this! Murilo Hello Bea,

Also, even though I use SQL directly, keep in mind that you can use Linq, NHibernate or your favorite technology to hook up to the data. My main goal was to highlight the WPF side of the solution and the overall thinking. Hope this helps. Bea Hi Jeff,

We had to move our displayed data to non-virtualized because of the very problem this solves. Keep up the great work! Can this also be done with the 3.5 framework? I can’t wait to try this out.
