Hi
I need urgently your help.
I am stuck to add new record.
I obtain a crash after submitChanges. I try all your samples and threads. I take sample from CRUID sample.
WHAT IS MISSING ??????????????

private void radGridView_AddingNewDataItem(object sender, GridViewAddingNewEventArgs e)
{ var form = new Form()
{  DateForm = app.lastDateForm,
     UserId = app.userId
};
e.NewObject = form;
DomainService2 context = this.formDomainDataSource.DomainContext as DomainService2;
context.Forms.Add(form);
}
private void radGridView_RowEditEnded(object sender, Telerik.Windows.Controls.GridViewRowEditEndedEventArgs e)
{
formDomainDataSource.SubmitChanges();
}
XAML is
<Grid.Resources>
<ria:DomainDataSource AutoLoad="False"
  x:Name="formDomainDataSource"
  QueryName="GetFormsByDateQuery" >
  <ria:DomainDataSource.DomainContext>
   <my:DomainService2 />
  </ria:DomainDataSource.DomainContext>
</ria:DomainDataSource>
</Grid.Resources>

<telerik:RadGridView
Visibility="Visible" x:Name="radGridView"
ShowInsertRow="True" ShowGroupPanel="False"
AutoGenerateColumns="True"
AddingNewDataItem="radGridView_AddingNewDataItem"
RowEditEnded="radGridView_RowEditEnded"
DataContext="{StaticResource formDomainDataSource}"
ItemsSource="{Binding Data}" IsBusy="{Binding IsBusy}">
</telerik:RadGridView>
