Re: Updating Crystal Report Data Source at runtime

Thank you so much Ludek.  You are a legend.   

That utility helped solve my problem.  It generated a piece of code which is a bit different approach than what I had written , it correctly updates the ODBC datasource at runtime.  (I have modified the code a bit. The utility generates code specific to report  (with table details etc), I have modified it because in my case, I don't know what reports User will be uploading and running. 

I will paste my code here in case it helps anyone else.

It all works well now on my machine, will try it on client's soon. 

using CrystalDecisions.ReportAppServer.DataDefModel;

using CrystalDecisions.CrystalReports.Engine;

using CrystalDecisions.Shared;

private void ViewCrystalReport()

    {

        try

        {

           CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();

            rpt.Load(FullReportPath);

            //Create a new Database Table to replace the reports current table.

            CrystalDecisions.ReportAppServer.DataDefModel.Table boTable = new CrystalDecisions.ReportAppServer.DataDefModel.Table();

            //boMainPropertyBag: These hold the attributes of the tables ConnectionInfo object

            PropertyBag boMainPropertyBag = new PropertyBag();

            //boInnerPropertyBag: These hold the attributes for the QE_LogonProperties

            //In the main property bag (boMainPropertyBag)

            PropertyBag boInnerPropertyBag = new PropertyBag();

            //Set the attributes for the boInnerPropertyBag

            boInnerPropertyBag.Add("DSN", "TEST");

            boInnerPropertyBag.Add("UseDSNProperties", "False");

            //Set the attributes for the boMainPropertyBag

            boMainPropertyBag.Add("Database DLL", "crdb_odbc.dll");

            boMainPropertyBag.Add("QE_DatabaseName", "");

            boMainPropertyBag.Add("QE_DatabaseType", "ODBC (RDO)");

            //Add the QE_LogonProperties we set in the boInnerPropertyBag Object

            boMainPropertyBag.Add("QE_LogonProperties", boInnerPropertyBag);

            boMainPropertyBag.Add("QE_ServerDescription", "TEST");

            boMainPropertyBag.Add("QE_SQLDB", "True");

            boMainPropertyBag.Add("SSO Enabled", "False");

            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo boConnectionInfo =

            new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();

            //Pass the database properties to a connection info object

            boConnectionInfo.Attributes = boMainPropertyBag;

            //Set the connection kind

            boConnectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;

            //**EDIT** Set the User Name and Password if required.

            boConnectionInfo.UserName = "TEST";

            boConnectionInfo.Password = "TEST";

            //Pass the connection information to the table

            boTable.ConnectionInfo = boConnectionInfo;

            //Get the Database Tables Collection for your report

            CrystalDecisions.ReportAppServer.DataDefModel.Tables boTables;

            boTables = rpt.ReportClientDocument.DatabaseController.Database.Tables;

            //For each table in the report:

            // - Set the Table Name properties.

            // - Set the table location in the report to use the new modified table

             for (int i = 0; i < boTables.Count; i++)

            {

                boTable.Name = rpt.ReportClientDocument.DatabaseController.Database.Tables[i].Name;

                boTable.QualifiedName = rpt.ReportClientDocument.DatabaseController.Database.Tables[i].QualifiedName;

                boTable.Alias = rpt.ReportClientDocument.DatabaseController.Database.Tables[i].Alias;

                rpt.ReportClientDocument.DatabaseController.SetTableLocation(boTables[i], boTable);

            }

            //Verify the database after adding substituting the new table.

            //To ensure that the table updates properly when adding Command tables or Stored Procedures.

            rpt.VerifyDatabase();

            //Simply display Report in Report Viewer

            CrystalReportViewer2.ReportSource = rpt;

        }

        catch (Exception ex)

        {

             ShowMessage(ex.Message);
