Implementing Document-View pattern I faced the problem: standard generic collections and dictionaries ( List<T>

  • 0

Implementing Document-View pattern I faced the problem: standard generic collections and dictionaries (List<T>, HashSet<T> for example) don’t provide events for modification (OnBeforeAdd, OnAfterAdd, OnRemove, Freeze/Unfreeze methods… )

I suppose events were not implemented for optimization purposes but I have to use and listen for such events using Document class.

I searched Inet for a while and found some demo implementations for lists. Is there well-known production-proved library with complete set of eventable generic collections/dictionaries or shall I implement such collections by myself?

Thank you in advance!

    you can wrap container to your own class and add events to that class.
