How to stop a feature layer edit save

DonFreeman

I am trying to validate an email address before proceeding with edits on a SDE feature layer. The edits are taking place via a FeatureDataForm. I have the following code.

  private void FeatureLayer_BeginSaveEdits(object sender, ESRI.ArcGIS.Client.Tasks.BeginEditEventArgs e)
  {
   Graphic SelectedGraphic = MyFeatureDataForm.GraphicSource;
   IDictionary<string, object> attributes = SelectedGraphic.Attributes;

   var msgToAM = attributes["AMEmail"] as string;
   var msgToPM = attributes["PMEmail"] as string;
   var msgToSat = attributes["WkEndEmail"] as string;
   var msgLocation = attributes["Location"] as string;

   if (SelectedFeatureLayer.ID == "AllAvailableFeatureLayer" )
   {
    if ((msgToAM.Length == 0 || msgToAM == "Type email here") & (msgToPM.Length == 0 || msgToPM == "Type email here"))
    {
     MessageBox.Show("Please provide a valid email address.");
     return ;
    }
   }
  }

This works but the save continues. How can I stop the save after the messagebox is displayed?
Thanks.

Just set e.Cancel = true;
