Use SetDatabaseLogon function

Myreport.SetDatabaseLogon("username", "password", "server", "dbname", false);

If SetDatabaseLogon function not working ...manually assign connection details to each table in the reports

ConnectionInfo connInfo = new ConnectionInfo();
connInfo.ServerName = "Driver={Adaptive Server      Enterprise};Server=x.x.x.x;Port=x;";
connInfo.UserID = "username";
connInfo.Password = "password";
TableLogOnInfo tableLogOnInfo = new TableLogOnInfo();
tableLogOnInfo.ConnectionInfo = connInfo;
foreach(Table table in reportDoc.Database.Tables)
{
   table.ApplyLogOnInfo(tableLogOnInfo);
    table.LogOnInfo.ConnectionInfo.ServerName =        connInfo.ServerName;
   table.LogOnInfo.ConnectionInfo.DatabaseName =      connInfo.DatabaseName;
   table.LogOnInfo.ConnectionInfo.UserID = connInfo.UserID;
  table.LogOnInfo.ConnectionInfo.Password = connInfo.Password;
   // Apply the schema name to the table's location
  table.Location = "dbo." + table.Location;
  }
