Get Entity properties modified after submitChanges on a DomainDatasSource

[GG]

Hi,

I have a RadGridView bound to a DomainDataService and I when I modify a cell in my GridView and then submitChanges() I would be able to retrieve the property modified and test if it is not null. How could I do that.

I look for listening to the event DomainDataSource_SubmittedChanges

private void DomainDataSource_SubmittedChanges(object sender, Telerik.Windows.Controls.DomainServices.DomainServiceSubmittedChangesEventArgs e)

{

    e.ChangeSet.GetChangeSetEntries() ...
}

And here I don't know how do I retrieve the value.
(My DomainDataSource use a query to retrieve an Entity from Entity Framework)

Thanks
