Crystal Report Viewer Next Page button does not work in ASP.NET

[former_member1118606]

I am using VS 2012 Ultimate , SAP Crystal Reports 13_0_13 (latest version). The problem is that when i click on crystal report viewer next Page button it goes on loading and never end, i am using the following code.

Protected void btn_Search_Click(object sender, EventArgs e)
{
     Session["ReportDocument"]=null;
     loadReport(Param1,Param2,param3,Param4);
}

load Report function

private void loadReport(string Param1, string Param2, string Param3,string Param4)
    {

            CrystalReportViewer1.Visible = true;
            ReportDocument reportDocument = new ReportDocument();
            string reportPath = Server.MapPath(@"~/VacantAndFilledReports/rpt_vacantposts_HR.rpt");
            reportDocument.Load(reportPath);
            reportDocument.SetDatabaseLogon(ID, pass, serverName, databaseName);
            reportDocument.SetParameterValue("@Param1", Param1);
            reportDocument.SetParameterValue("@Param2", Param2);
            reportDocument.SetParameterValue("@Param3", Param3);
            reportDocument.SetParameterValue("Param4", Param4);
            reportDocument.SetParameterValue("Title", FundName);
            CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;
            CrystalReportViewer1.AutoDataBind = true;
            CrystalReportViewer1.Zoom(88);
            CrystalReportViewer1.ReportSource = reportDocument;
            Session["ReportDocument"] = reportDocument;

    }

I have also put the code in Page_Init

 protected void Page_Init(object sender, EventArgs e)
    {
        if (Session["ReportDocument"] != null)
        {
            //Response.Write("Hello");
            ReportDocument doc = (ReportDocument)Session["ReportDocument"];
            CrystalReportViewer1.ReportSource = doc;
        }
    }

I have searched a lot regarding Page Next Button of crystal report viewer but all there was to put code inside Page_Init, i tried as above but did't get the solution and still it is on Page 1 and does not go to Page 2.

Please tell me where i am doing wrong?

Add Session code to keep the report in session and a postback method to tell the report it is in an active session.

Search, there are sample available.
