HI,

 Create a style targeting the LabelPresenter and wire up the PreviewMouseRightButtonDown Event.

<Style TargetType="{x:Type igDP:LabelPresenter}">
                <EventSetter Event="PreviewMouseRightButtonDown" Handler="xgrid1_PreviewMouseRightButtonDown"/>
            </Style>

  private void xgrid1_PreviewMouseRightButtonDown(object sender, MouseButtonEventArgs e)
        {
            LabelPresenter lp = sender as LabelPresenter;
            MessageBox.Show(lp.Field.Name);
        }

Sincerely,
Matt
