Event Data

The BeforeRollbackTransaction event's data class is SessionManipulationEventArgs. The following properties provide information specific to this event:

Property	Description
Session	Gets the session currently being processed.

Remarks

The ROLLBACK operation (Session.RollbackTransaction or ExplicitUnitOfWork.RollbackTransaction) discards all data modifications made since the start of the transaction and completes the transaction. As a result, the BeforeRollbackTransaction event is raised. The event parameter’s SessionManipulationEventArgs.Session property allows the current session to be identified.

After the transaction has been completed, via the ROLLBACK operation, the Session.AfterRollbackTransaction event is raised.
