BaseObjectSpace.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

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public event EventHandler<HandledEventArgs> CustomCommitChanges

VB.NET

Public 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.

Remarks

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

As an alternative to this event, you can override the DoCommit method in the BaseObjectSpace class’ descendant.
