Adds the specified object to the Collection Source's CollectionSourceBase.Collection.
An object that must be added to the Collection Source's collection.
Generally, you do not have to call this method. If you have instantiated an CollectionSourceBase.ObjectTypeInfo.Type persistent object, and want it to appear in a List View, save it and call the View.Refresh method.
When implementing a custom Collection Source, override this method to add the specified object to the Collection Source's collection.
