Use StatusFilter to limit the client dataset to records that represent a specific update status. This can be useful when processing updates in a provider's event handlers (or, if the client dataset has an internal provider, in its own BeforeUpdateRecord event handler). 

StatusFilter is a set of TUpdateStatus values. It can indicate more than one type of update. If StatusFilter is an empty set (the default), the client dataset appears as if all updates in the change log have been incorporated. 

Including usUnmodified in StatusFilter has no effect.
