    HI Pokrec,

     If you are using s DataTable with a unique key defined. The XamDataGrid's DataError event will fire when the unique constraint is violated.

     Here a code snippet

      void xgrid_DataError(object sender, Infragistics.Windows.DataPresenter.Events.DataErrorEventArgs e)
            {
                //throw new NotImplementedException();

                MessageBox.Show(e.Exception.Message.ToString());
                e.Handled = true;
            }

      Sincerely,
