how to create common HTML form to display multiple crystal?

Question

I have various crystal report rpt files and displaying as a popup if click on report button in html form.

my code is on main form

CrystalDecisions.CrystalReports.Engine.ReportDocument theReport = new CrystalDecisions.CrystalReports.Engine.ReportDocument();

theReport.Load(MapPath(".") + "\\Reports\\WCS_ConsignmentAdvice.rpt");

//theReport.SummaryInfo.ReportTitle = "Account Transaction Details ( per Transaction ) Inquiry";

dstemp.Tables[0].TableName = "ConsignmentAdvice";

theReport.SetDataSource(dstemp);

Session["exporttopdf"] = theReport; 

 

I am sending this report document object to html popup form and in my popup form code is

theReport = ( CrystalDecisions.CrystalReports.Engine.ReportDocument ) Session["exporttwopdf"];

System.IO.MemoryStream m;

m = (System.IO.MemoryStream)theReport.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat );

theReport.Close ();

this.Response.ClearContent();

this.Response.ClearHeaders();

this.Response.AddHeader("Title", "Report");

this.Response.ContentType="Application/pdf";

this.Response.Buffer=true;

this.Response.BinaryWrite (m.ToArray());

this.Response.Flush();

this.Response.End ();

Session["exporttwopdf"] = null;
