C# เรียกใช้งาน Crystal Reports แล้วมันถามหา username pass ของฐานข้อมูล

      ReportDocument cryRpt = new ReportDocument(); 
     TableLogOnInfos crtableLogoninfos = new TableLogOnInfos(); 
     TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); 
     ConnectionInfo crConnectionInfo = new ConnectionInfo(); 
     Tables CrTables;
     cryRpt.Load("D:\\Report1.rpt"); 
        crConnectionInfo.ServerName = "CHOKSIMA_MATERIAL_MANAGEMENT_PRO"; 
        crConnectionInfo.DatabaseName = "CHOKSIMA_MATERIAL_MANAGEMENT_PRODUCT"; 
        crConnectionInfo.UserID = "*********"; 
        crConnectionInfo.Password = "*********"; 
        CrTables = cryRpt.Database.Tables; 
        foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables) {    
            crtableLogoninfo = CrTable.LogOnInfo;    
            crtableLogoninfo.ConnectionInfo = crConnectionInfo;    
            CrTable.ApplyLogOnInfo(crtableLogoninfo); 
               }
            crystalReportViewer1.ReportSource = cryRpt; 
            crystalReportViewer1.RefreshReport();

cryRpt.Load(Server.MapPath("Rpt/Report1.rpt"));
