title: Labels do not disappear
body: <p>On a report I have a grouptxt.
  On opening I'm trying to manipulate some labels.
  When Rit = 0 then the labels and txt should be true or false (see below).
  But it doesn't work.</p>
  
  <pre class="lang-vb prettyprint-override"><code>Private Sub Groepskoptekst1_Format(Cancel As Integer, FormatCount As Integer)
      If Me.Rit = 0 Or IsNull(Me.Rit) Then
          Me.lblDatum.Visible = True
          Me.Datum.Visible = True
          Me.Rit.Visible = False
          Me.lblRit.Visible = False
          Me.GeenRit.Visible = True
          Me.Traject.Visible = False
          Me.lblKm.Visible = False
      Else
          Me.lblDatum.Visible = True
          Me.Datum.Visible = True
          Me.Rit.Visible = True
          Me.lblRit.Visible = True
          Me.GeenRit.Visible = False
          Me.Traject.Visible = True
