  For save report as PDF file I wrote:
  
  string tempFolder = Path.GetTempPath() + "_" + Guid.NewGuid().ToString();
  string filepath = tempFolder + "\\Result.pdf";
  
  if (!Directory.Exists(tempFolder))
  {
  Directory.CreateDirectory(tempFolder);
  }
  
  FastReport.Export.Pdf.PDFExport export = new FastReport.Export.Pdf.PDFExport();
  
  export.OpenAfterExport = false;
  
  WebReport1.Report.Export(export, filepath);
  
  
  
  
  System.IO.Stream iStream = null;
  
  // Buffer to read 10K bytes in chunk:
  byte[] buffer = new Byte[100000];
  
  // Length of the file:
  int length;
  
  // Total bytes to read:
  long dataToRead;
  
  // Identify the file to download including its path.
  //string filepath = "DownloadFileName";
  
  // Identify the file name.
  string filename = System.IO.Path.GetFileName(filepath);
  
  try
  {
  // Open the file.
  iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open,
  System.IO.FileAccess.Read, System.IO.FileShare.Read);
  
  // Total bytes to read:
  dataToRead = iStream.Length;
  
  Response.ContentType = "application/octet-stream";
  Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);
  
  // Read the bytes.
  while (dataToRead > 0)
  {
  // Verify that the client is connected.
  if (Response.IsClientConnected)
  {
  // Read the data in buffer.
  length = iStream.Read(buffer, 0, 100000);
  
  // Write the data to the current output stream.
  Response.OutputStream.Write(buffer, 0, length);
  
  // Flush the data to the HTML output.
  Response.Flush();
  
  buffer = new Byte[100000];
  dataToRead = dataToRead - length;
  }
  else
  {
  //prevent infinite loop if user disconnects
  dataToRead = -1;
  }
  }
  }
  catch (Exception ex)
  {
  // Trap the error, if any.
  Response.Write("Error : " + ex.Message);
  }
  finally
  {
  if (iStream != null)
  {
  //Close the file.
  iStream.Close();
  }
  Response.Close();
  }
  
  works perfect
