DomainDataSource.SubmittingChanges Event

WCF RIA Services

[WCF RIA Services Version 1 Service Pack 2 is compatible with either .NET framework 4 or .NET Framework 4.5, and with either Silverlight 4 or Silverlight 5.]

Occurs whenever a submit operation is started.

Namespace:  System.Windows.Controls
Assembly:  System.Windows.Controls.DomainServices (in System.Windows.Controls.DomainServices.dll)

Public Event SubmittingChanges As EventHandler(Of SubmittingChangesEventArgs)
Dim instance As DomainDataSource
Dim handler As EventHandler(Of SubmittingChangesEventArgs)

AddHandler instance.SubmittingChanges, handler

This event is raised from SubmitChanges and enables a handler to cancel the submit before it starts. When a handler sets Cancel to true, the submit will be aborted and a subsequent SubmittedChanges event will not be raised. This differs slightly from canceling a submit by way of CancelSubmit.
