The key to this is write an implementation of IList that throws ItemPendingErrors and then does the loading for you. You then pass that IList to aListCollectionView and away you go. Keep in mind that if you attempt to sort or filter the ListCollectionView will try to load all of your data, so you'll need to do your own work to have that passed through (which may mean subclassing LCV or writing your own impl of ICollectionView if this is important to you).

Actually, I would love to use FDS, but unfortunately this app requires a .NET backend and doesn't have the budget for FDS or WebOrb anyway.
