IObjectSpace.CustomCommitChanges Event

Replaces the default process for committing changes made to persistent objects with a custom one.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v20.2.dll


event EventHandler<HandledEventArgs> CustomCommitChanges
Event CustomCommitChanges As EventHandler(Of HandledEventArgs)

Event Data

The CustomCommitChanges 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.


The CustomCommitChanges event is raised as a result of calling the IObjectSpace.CommitChanges method. Handle this event to provide a custom process of committing the changes made to the current Object Space's persistent objects. Set the handler's CompletedEventArgs.Handled parameter to true, to indicate that the commit operation has been already performed.

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 CustomCommitChanges event, since it is raised by the BaseObjectSpace.CommitChanges method.
