Open mutiple PDF report outputs with one button click

Question

I need to open multiple PDF outputs depending on check boxes on the front end (Asp.net C#) app connecting to Crystal report server XI. Here is my code. I'm able to open only one PDF not multiple. If I use Response.end() at the end except first nothing is displayed. If I remove response.end() it opens Adobe and displays error msg saying file is corrupted. Please let me know if there is any other way to display multiple PDF outputs
SessionMgr sessionMgr = new SessionMgr();
        EnterpriseSession enterpriseSession;
        ReportAppFactory reportAppFactory;
        ReportClientDocument reportClientDocument;
        EnterpriseService enterpriseService;
        InfoStore infoStore;
        InfoObjects infoObjects;
        InfoObject infoObject;
        String crServerName = ConfigurationManager.AppSettings.Get("CRServerName");
        String crUserID = ConfigurationManager.AppSettings.Get("CRUserID");
        String crPwd = ConfigurationManager.AppSettings.Get("CRPwd");
        String dbUserID = ConfigurationManager.AppSettings.Get("DBUserID");
        String dbPwd = ConfigurationManager.AppSettings.Get("DBPwd");
        enterpriseSession = sessionMgr.Logon(crUserID, crPwd, crServerName, "secEnterprise");
        enterpriseService = enterpriseSession.GetService("InfoStore");
        infoStore = new InfoStore(enterpriseService);
        infoObjects = infoStore.Query("Select SI_ID From CI_INFOOBJECTS Where SI_NAME='" + reportName + "' And SI_INSTANCE=0");
        infoObject = infoObjects[1];
        EnterpriseService tempService = enterpriseSession.GetService("", "RASReportFactory");
        reportAppFactory = (ReportAppFactory)tempService.Interface;
        reportClientDocument = reportAppFactory.OpenDocument(infoObject.ID, 0);
        // Pass datbase logon credentials
        reportClientDocument.DatabaseController.logon(dbUserID, dbPwd);
reportClientDocument.DataDefController.ParameterFieldController.SetCurrentValues("", "ProjectID", ddlProjects.SelectedValue);
        PrintOutputController rasPrintOutputController;
           CrReportExportFormatEnum rasReportExportFormat = CrReportExportFormatEnum.crReportExportFormatPDF;
                       rasPrintOutputController = doc.PrintOutputController;
            ByteArray tempByteArray = rasPrintOutputController.Export(rasReportExportFormat, 0);
            Byte[] byteStreamOutput = tempByteArray.ByteArray;
            Response.AddHeader("content-disposition", "attachment;filename=" + reportName + ".pdf");
           Response.ContentType = "application/pdf";
            Response.BinaryWrite(byteStreamOutput);
Response.end();

Hello, Anu;
Business Objects will create one PDF from one report. Once the report object has been formatted as a PDF it is no longer handled by Business Objects but uses the functionality of Adobe.
If they were being saved as .pdf files, would there be a way to open more than one at a time?
