IObjectSpace.CustomRollBack Event
Replaces the default process of persistent objects rollback with a custom one.
Namespace: DevExpress.ExpressApp
Assembly: DevExpress.ExpressApp.v18.2.dll
Declaration
Event Data
The CustomRollBack event's data class is HandledEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Handled | Gets or sets a value that indicates whether the event handler has completely handled the event or whether the system should continue its own processing. |
Remarks
The CustomRollBack event is raised as a result of calling the IObjectSpace.Rollback method. Handle this event to provide a custom process for rolling back the current Object Space’s persistent objects. Set the handler’s CompletedEventArgs.Handled parameter to true to indicate that the rollback has already been performed. Set the handler’s CompletedEventArgs.IsCompleted parameter to true in the case of a successful rollback; otherwise, set false. This value will be returned by the IObjectSpace.Rollback method.
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 CustomRollBack event, since it is raised by the BaseObjectSpace.Rollback method.
