SSRS Rectangle in SubReport

I have a created SSRS Report with 5 Subreports.All my SubReports have Header. unfortunately these headers won't display in the main report so I removed the header and put all the header content into a rectangle and set the repeat with the property to the My table in the report.All is well so far .But When i exported to PDF the Rectangle only displayed in the first page of the subreport .But I want to show this rectangle(Header) for all the pages in the subreport. Can anybody please advice How can i achieve this?

Thanks
