Database logon failed when opening report with parameter values in CrystalReportViewer

Question

Hi,
I designed 2 crystal reports: report A contains parameter fields and report B did not contain any parameter
I can open both reports in development site using CrystalReportViewer control. When I open the reports in testing site,
I can open report B but can't open report A. It display error message "Database logon failed". When I set EnableDatabaseLogonPrompt
to true and try to open the report A again, it shows database connection data which was created on report.
In addition, it is strange that it displays error "Database logon failed" when I click an item in group tree panel of the report B. This indicates that it can load data from database
in testing site but it connect to development database when clicking items in group tree panel
All reports connect to database using Windows Authenication. It use dynamic database connection at runtime
How to ensure the report always connect database using login data dynamically at runtime?
Below is my code about database connection:
string strServerName = null;
string strDatabaseName = null;
ReportDocument rptDoc = new ReportDocument();
rptDoc.Load(strFilePath);
ConnectionInfo connInfo = new ConnectionInfo();
TableLogOnInfo logonInfo;
for (int i = 0; i < rptDoc.Database.Tables.Count; i++)
logonInfo = rptDoc.Database.Tables[i].LogOnInfo;
ReportHelper.GetReportConnection(ref strServerName, ref strDatabaseName, strSystemType);
logonInfo.ConnectionInfo.ServerName = strServerName; 
logonInfo.ConnectionInfo.DatabaseName = strDatabaseName;
logonInfo.ConnectionInfo.IntegratedSecurity = true;
rptDoc.Database.Tables[i].ApplyLogOnInfo(logonInfo);
rptDoc.Database.Tables[i].Location = rptDoc.Database.Tables[i].Location.Substring(0, rptDoc.Database.Tables[i].Location.Length - 2);
crvViewer.ReportSource = rptDoc;
crvViewer.DataBind();
Development environment:
- SAP Crystal Reports 2013 Support Pack 1
- Visual Studio Professional 2012
- .NET Framework 3.5
- DDL
CrystalDecisions.Shared (v 13.0.8.1216)
CrystalDecisions.Web (v 13.0.8.1216)
CrystalDecisions.CrystalReports.Engine (v 13.0.8.1216)
Database connection in crystal report:
- Database Type: OLEDB (ADO)
- Provider: SQLOLEDB
- Integrated Security: True
Thanks and Regards,
Tony

Hi Tonylck
Try  to pass login info to crystal report dynamically as follows:
using System;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
namespace WindowsApplication1
public partial class Form1 : Form
public Form1()
InitializeComponent();
private void button1_Click(object sender, EventArgs e)
ReportDocument cryRpt = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables ;
cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt");
crConnectionInfo.ServerName = "YOUR SERVER NAME";
crConnectionInfo.DatabaseName = "YOUR DATABASE NAME";
crConnectionInfo.UserID = "YOUR DATABASE USERNAME";
crConnectionInfo.Password = "YOUR DATABASE 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.Refresh();
