You can do that by calling DataContext.invalidateObjects(Collection).

As this method only partially restores the object graph (unlike
"rollbackChanges()"), there maybe undesired consequences. Namely if
"deleted" object's Entity had "cascade" or "nullify" delete rules setup
in the modeler for relationships, affected related objects will not be
restored.
