Page settings in VB.NET 2005 ReportViewer

I'm pretty new to the ReportViewer control in VB.NET 2005.

I have made a report, which works well.
But the ReportViewer controll doesn't seem to use the margins defined in the report. Also I would like to set the paper size default to A4 and the orientation to Landscape.
I can't find how to do this.
Now the report is default at letter size and portait, which causes the report to spread across 2 pages wide.

Anybody can help?

Hi Frans.
Is not the reportviewer but the report itself.
[vbcode]
crReportDocument.PrintOptions.PaperOrientation = PaperOrientation.Landscape
crReportDocument.PrintOptions.PaperSize = PaperSize.PaperA4
[/vbcode]

I am not using the cristal report but the Microsoft.Reporting.WinForms.ReportViewer control with an rdlc file

oops never used that control.
