ASp.NET MVC+CrystalReportViewer+ веб-формы

Question

У меня есть CrystalReportViewer в веб-форме, и я загружаю отчет динамически, передавая параметры. Все эти данные находятся в методе Page_Load. Работает нормально и отчет загружается. Но при нажатии "Следующая страница" средство просмотра отчетов не перемещается мимо страницы 2. Похоже, что отчет загружается при нажатии кнопки "Следующая страница" и устанавливается текущая страница средства просмотра. Мой код ниже:

protected void Page_Load(object sender, EventArgs e)
        {            
            //if (!Page.IsPostBack)
            {
                string reportPath = Request.QueryString["ReportName"];
                string parameters = Request.QueryString["Parameters"];                    
                LoadReport(reportPath, parameters);
            }
        }

private void LoadReport(string ReportPath, string RptParams)
        {
            CrystalDecisions.Shared.TableLogOnInfo ConInfo = new CrystalDecisions.Shared.TableLogOnInfo();

            ParameterValues crParameterValues;
            ParameterDiscreteValue crParameterDiscreteValue;
            ParameterFieldDefinitions crParameterFieldDefinitions;
            ParameterFieldDefinition crParameterFieldDefinition;

            string[] strParValPair;
            string[] strVal;
            int index;
            String paramInfoMsg = "";
            int TableCounter;

            String ReportName = ReportPath.Substring(ReportPath.LastIndexOf("/") + 1);

            try
            {                    
                string relPath = Server.MapPath(ReportPath);
                objReport.Load(relPath);                    

                crParameterFieldDefinitions = objReport.DataDefinition.ParameterFields;

                //Set the connection information to ConInfo object so that we can apply the 
                //connection information on each table in the report

                ConInfo.ConnectionInfo.UserID = System.Configuration.ConfigurationManager.AppSettings["UserID"];
                ConInfo.ConnectionInfo.Password = System.Configuration.ConfigurationManager.AppSettings["Password"];
                ConInfo.ConnectionInfo.ServerName = System.Configuration.ConfigurationManager.AppSettings["ServerName"];
                ConInfo.ConnectionInfo.DatabaseName = System.Configuration.ConfigurationManager.AppSettings["DatabaseName"];

                String RootReportSPLocation = ConInfo.ConnectionInfo.DatabaseName + "." + ConInfo.ConnectionInfo.UserID + ".";

                for (TableCounter = 0; TableCounter < objReport.Database.Tables.Count; TableCounter++)
                {
                    objReport.Database.Tables[TableCounter].ApplyLogOnInfo(ConInfo);

                    try
                    {                            
                        if (objReport.Database.Tables[TableCounter].Location.Trim() == "") // only fall back on this code if the Location doesn't already exist
                            if (objReport.Database.Tables[TableCounter].TestConnectivity()) // comment out this block should Report Running cause app crashes again, with any luck the above IF statement resolved them
                                objReport.Database.Tables[TableCounter].Location = ConInfo.ConnectionInfo.DatabaseName + "." + ConInfo.ConnectionInfo.UserID + "." + objReport.Database.Tables[TableCounter].Location.Substring(objReport.Database.Tables[TableCounter].Location.LastIndexOf(".") + 1); //RootReportSPLocation + objReport.Database.Tables[TableCounter].Location.Substring(objReport.Database.Tables[TableCounter].Location.LastIndexOf(".") + 1);
                    } // From what was experienced even with the Try/Catch present an Informix DLL (iclit09b.dll) is crashing which occurs outside our scope so it CAN'T be caught
                    catch (Exception) { }
                }

                //set the crSections object to the current report's sections
                Sections crSections = objReport.ReportDefinition.Sections;

                //loop through all the sections to find all the report objects

                        {
                            // You will need to typecast the reportobject to a subreport object once you find it
                            SubreportObject crSubreportObject = (SubreportObject)crReportObject;

                            // Open the subreport object
                            ReportDocument crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName);

                            for (TableCounter = 0; TableCounter < crSubreportDocument.Database.Tables.Count; TableCounter++)
                            {
                                crSubreportDocument.Database.Tables[TableCounter].ApplyLogOnInfo(ConInfo);
                                // The main report seems to work without this so we might consider removing it here or put an additional check to see if it is necessary
                                crSubreportDocument.Database.Tables[TableCounter].Location = RootReportSPLocation + crSubreportDocument.Database.Tables[TableCounter].Location.Substring(crSubreportDocument.Database.Tables[TableCounter].Location.LastIndexOf(".") + 1);

Эта проблема не является CrystalReportViewer. Любая помощь приветствуется.
