 var lst = new List<PdfReader>();
                        for (var i = 0; i <= dt.Rows.Count - 1; i++)
                        {
                            var fileExist =
                                new FileInfo(
                                    System.Web.HttpContext.Current.Server.MapPath(dt.Rows[i]["FileName"].ToString()));
                            if (fileExist.Exists)
                            {
                                var reader =
                                    new PdfReader(
                                        System.Web.HttpContext.Current.Server.MapPath(dt.Rows[i]["FileName"].ToString()));
                                lst.Add(reader); // [i] = reader;
                            }

                        }
new Document(PageSize.A4);
                          var size = lst[0].GetPageSizeWithRotation(1);
                          var document = new Document(size);
                          var writer = PdfWriter.GetInstance(document,
                                                             new FileStream(
                                                                 System.Web.HttpContext.Current.Request.
                                                                     PhysicalApplicationPath + "PrintFiles/" + rndnumber +
                                                                 "~SamplePDFRoutingOrder1.pdf", FileMode.Create,
                                                                 FileAccess.Write));
                          document.Open();
                          var jAction = PdfAction.JavaScript("this.print(true);\r", writer);
                          writer.AddJavaScript(jAction);
                          var cb = writer.DirectContent;
                          foreach (var reader in lst)
                          {
                              for (var pageNumber = 1; pageNumber <= reader.NumberOfPages; pageNumber++)
                              {
                                  document.NewPage();
                                  var page = writer.GetImportedPage(reader, pageNumber);
                                  cb.AddTemplate(page, 0, 0);
                              }
                          }
                          document.Close();
 _currentView.SetPdf(rndnumber);

public void SetPdf(Int64 randomNumber)
   {
       iframe1.Attributes["src"] = "PrintFiles/" + randomNumber + "~SamplePDFRoutingOrder1.pdf";
   }
