How to hide the page header if there are no detail records on that page?

I have a report where the report footer bleeds over to the last (empty page) forcing the PageHeader to print on the last empty (except for the report footer) page.
I've tried the following without success:
void PageFooter_BeforePrint(object sender, EventArgs e) {
   object row = this.GetCurrentRow();
   if (row == null)
        e.Cancel = true;
}
This does not work since row is never null.
I've tried setting PageHeader.PrintOn to NotWithReportFooter - this does not work also because it separates the PageHeader from ReportFooter always - not what I want.
I did the following, which does work:
private int rowCounter = 0;
            Detail.AfterPrint += (o, args) => { rowCounter++; };
            PageHeader.BeforePrint += (o, args) =>
            {
                if (rowCounter >= this.RowCount)
                    args.Cancel = true;
            };
but it's a hack and real ugly.
Please tell me there is a better way to handle this.
