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)

'Declaration
Public Event SubmittingChanges As EventHandler(Of SubmittingChangesEventArgs)
'Usage
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.
