When I try to add a GroupDescriptor to my CompositeCollection I get an exception informing me that the CompositeCollection does not supporting grouping.

I would like to know if anyone has found a good work around for this limitation. I have two collections which I am "zipping" together and trying to group. If it is any help, I am not interested in grouping between the collections, just with in the collections them selves.

Use CollectionViewSource on your CompositeCollection, please take a look at How to handle a CompositeCollection with CollectionView features?.

    CollectionViewSource on CompositeCollection does not support grouping, so how exactly does your answer solve the problem? – Raúl Nuño Mar 23 '18 at 20:58
