RDLC Report Definition - adding field values into a Header

In an RDL(C) Report definition, we cannot use regular field expression like the following, in the Header:

=First(Fields!LicNo.Value)

Instead, if there is a text element named 'LicNo' in the main page of the report,
then inside the header we can refer to the text element:

=ReportItems!LicNo.Value

We can make the text element be hidden if we do not want to show it on the main page of the report
(Properties -> Visibility -> Hidden = true)
