Programmatically trigger export and print commands in report viewer

Question

Since I have not been able to intercept the events "print" and "export" of report viewer in asp.net (my previous question). I am now considering to trigger programmatically these two functions using buttons.

Is there anyone that has been able to achieve this in a report viewer asp.net? I mean to trigger "print" and "export to pdf" in the report viewer where these controls are set to non visible?

ReportViewer1.PrintDialog() seems to work. I'm not sure about export though.

Export:

private void DoExport(string exportType) {
  Warning[] warnings;
  string[] streamids;
  string mimeType;
  string encoding;
  string extension;
  string filename;

  byte[] bytes = reportViewer.LocalReport.Render(
     exportType, null, out mimeType, out encoding,
      out extension,
     out streamids, out warnings);

  filename = string.Format("report-{0:yyyy-MM-dd}.{1}", DateTime.Now, extension);
  Response.ClearHeaders();
  Response.Clear();
  Response.AddHeader("Content-Disposition", "attachment;filename=" + filename);
  Response.ContentType = mimeType;
  Response.BinaryWrite(bytes);
  Response.Flush();
  Response.End();
}

protected void btnExportToExcel_Click(object sender, EventArgs e) {
  DoExport("Excel");
}

protected void btnExportToPdf_Click(object sender, EventArgs e) {
  DoExport("Pdf");
}

Not sure about the print (how can you trigger client side functionality on server anyway ? ;)
