Hello Telerik. We're attempting to use data virtualization with gridview and have run into a mystical problem.
We have a bunch of Entities inheriting from a base class EdgeObjectDTO, which we put in a VirtualQueryableCollectionView<EdgeObjectDTO> object. But sometimes when new items are about to be loaded we get an invalid cast exception in GridViewCellsPanel.Virtualization.cs (see screenshot). The crazy thing with this cast is it seems to be in the wrong direction (from base class to derived class).
Do you have any insight on this?
We're using the 2011_1_0606_DEV_hotfix build.
Best regards,
Patrik Edberg
