Occurs before saving the persistent objects belonging to the current Object Space to the database.
The Committing event is raised before committing persistent objects as a result of calling the IObjectSpace.CommitChanges method. Handle this event to prevent saving object changes to the database. For this purpose, set the handler's CancelEventArgs.Cancel parameter to true. By default, this parameter is set to false.
If you implement the IObjectSpace interface in the BaseObjectSpace class' descendant, you should override the BaseObjectSpace.DoCommit method which is called by the BaseObjectSpace.CommitChanges method. In this instance, you won't have to raise the Committing event, since it is raised by the BaseObjectSpace.CommitChanges method.
