Occurs before rolling back the changes made to the current Object Space's persistent objects.
The RollingBack event's data class is CancelEventArgs. The following properties provide information specific to this event:
|Cancel||Gets or sets a value indicating whether the event should be canceled.|
The RollingBack event is raised before updating persistent objects as a result of calling the IObjectSpace.Rollback method. Handle this event to prevent objects from rolling back. 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.Reload method which is called by the BaseObjectSpace.Rollback method. In this instance, you won't have to raise the RollingBack event, since it is raised by the BaseObjectSpace.Rollback method.
