Q: 

Work around for lack of Grouping in CompositeCollection

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.

+2  A: 

Use CollectionViewSource on your compositecollection, please take a look at http://stackoverflow.com/questions/2079553/how-to-handle-a-compositecollection-with-collectionview-features.
