Sub PopupMenu1OnPopup(Sender: Object; Args: IPopupMenuEventArgs);
Var
    Br: IBreadcrumb;
    Elem: Integer;
Begin
    If Args.Control Is Breadcrumb Then
        Br := Args.Control As IBreadcrumb;
        Elem := Br.HitTest(Args.Point);
        If Elem <> -1 Then
            Debug.WriteLine(Br.Items.Item(Elem).Text);
        End If;
    End If;
End Sub PopupMenu1OnPopup;
