Changing Database connection at runtime in CR2008

Question

Hi,
I have a VS2008 application which is using CR2008 to generate pdf reports for the user. Problem is I am not able to change the database connection to any server other than the one that was used to create the report template.
My environment has CR2008 SP2. I have tried reports with no paramter as well as the ones with parameters both dont seem to work.
I have already tried a couple of things:
a) report document refresh after loading it
b) setting the database connection as
this._crReport.DataSourceConnections[0].SetConnection(dbServerName, dbName, dbUserId, dbPwd);
c) setting the database connection as
tbls = this._crReport.Database.Tables;
                bool test = false;
                foreach (Table tbl in tbls)
                    tblLogonInfo = tbl.LogOnInfo;
                    tblLogonInfo.ConnectionInfo = connInfo;
                    tbl.ApplyLogOnInfo(tblLogonInfo);
                    test = tbl.TestConnectivity(); ** note this alwys return a true for the changed database server
I have read a couple of thread but none has worked for me...Is this a known issue with CR2008?
Thanks

Hi Kajal,
I am assuming that you are not changing the schema of the report at any point of time. I would suggest you to try pointing to the other database through designer to make sure that you can hit the database and the schema is correct. You can also create a udl file to check the database connectivity.
Then just for testing purpose you can try the following code:
ReportDocument reportDoc = new ReportDocument();
reportDoc.Load("path of the report");
reportDoc.SetDatbaseLocation("uid","pwd","Servername","tablename");
reportDoc.SetParameterValues("Parameter-Name","values");
CrystalReportViewer.ReportSoure=reportDoc;
Does that help?
Thanks.
