Transaction Roll |
Rolls back all changes made to the model during the transaction.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax Return Value
TransactionStatusIf finished successfully, this method returns TransactionStatus.RolledBack.
Be aware that the returned status does not have to be necessarily the same like the status returned by GetStatus even when the method is called immediately after rolling back the transaction. Such difference may happen due to actions made by a transaction finalizer, if there was one set. (See FailureHandlingOptions for more details.)
Exceptions | Exception | Condition |
|---|---|
| InvalidOperationException | The current status of the transaction is not 'Started'. Transaction must be started before calling Commit or Rollback. -or- The transaction's document is currently in failure mode. No transaction operations are permitted until failure handling is finished. |
Remarks By rolling back a transaction, all changes made to the model are discarded. RollBack may only be called for a transaction that has been started. (Use the GetStatus method to check the current state.) Be aware that rolling back may be delayed (as a result of failure handling.) Callers should always check the returned status to test whether a transaction was rolled back successfully. Only after rolling back is fully completed, the transaction may be started again.
