Hi
Iam using VS-2010. Windows Applications. The below codes to save the report as PDF in c#...But I wish to save the particular part of report as PDF...

Note:
Suppose My report contains 4-Copies with 8 pages, my intention is to save only the
"Transporter Copy" as mentioned in Report Header area.
Is it possible to save only the particular copy of reportviewer's report...?

Thanks

My Codes

byte[] Bytes = Reportviewer1.LocalReport.Render(format:"PDF",deviceInfo:""); 
using (FileStream stream = new FileStream("C:\MyFolder", FileMode.Create)) 
{
 stream.Write(Bytes, 0, Bytes.Length); 
}
