With DeConceptoNAS
     If .rsSQLlisteParticipant.State <> 0 Then .rsSQLlisteParticipant.Close
     .SQLlisteParticipant CDate(DTPickerDebut.Value),
CDate(DTPickerFin.Value)
   End With
   RptConceptoNAS.Refresh
   If Not RptConceptoNAS.Visible Then RptConceptoNAS.Show

The data show is correctly.

But now I want to show the date range in my report title (ReportHeader).

How can this be done ?

While can I use a RptTextBox the ReportHeader section only RptLabel ?

Thanks in advance for your help
