c# - Has anyone got a solution/workaround for CollectionContainer not being Freezable? -

-

i'm trying bind source of collectioncontainer (or collectionviewsource matter) relativesource binding - following error

system.windows.data error: 2 : cannot find governing frameworkelement or frameworkcontentelement target element.

i understand due collectioncontainer not being freezable or not deriving frameworkelement.

has got solution/workaround problem. have seen talk of trying implement own freezable collectioncontainer - luck approach?

thanks, pete
