I am implementing a custom virtual collection similar to the VirtualQueryableCollectionView. The difference is mine allows for adding and deleting items.
I fill my collection with a set of null values based on the VirtualItemCount and I need to know which entities to load when the user is scrolling.
How do you trigger LoadItems in your VirtualQueryableCollectionView?
I have tried to get the row index when the scroll changes by listening to RowLoaded. But gridView.Items.IndexOf(e.DataElement) does not work because DataElement is null.
Do you have any solution to get the row index?

Finally figured out how to use the decompiler in my code assist :)
By overriding: GetItemAt(int index) I was able to implement this.
