title: ASP.Net CrystalReportViewer just rendering vertical lines
body: <p>I have a plain asp.Net page that contains a CrystalReportViewer.  I use the following code to in the Page_Load method to display a report:</p>
  
  <pre><code>ReportDocument report = new ReportDocument();
                      TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
                      TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
                      ConnectionInfo crConnectionInfo = new ConnectionInfo();
                      Tables CrTables;
  
                      report.Load(Server.MapPath("Reports\\" + Request.Params[0]));
  
                      crConnectionInfo.ServerName = ConfigurationManager.AppSettings["ReportSQLServer"];
                      crConnectionInfo.DatabaseName = ConfigurationManager.AppSettings["ReportSQLDatabase"];
                      crConnectionInfo.UserID = ConfigurationManager.AppSettings["ReportSQLUsername"];
                      crConnectionInfo.Password = ConfigurationManager.AppSettings["ReportSQLPassword"];
  
                      CrTables = report.Database.Tables;
                      foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
                      {
                          crtableLogoninfo = CrTable.LogOnInfo;
                          crtableLogoninfo.ConnectionInfo = crConnectionInfo;
                          CrTable.ApplyLogOnInfo(crtableLogoninfo);
                      }
  
                      Session["Report"] = report;
                      rptViewer.ReportSource = report;
                      rptViewer.RefreshReport();
  </code></pre>
  
  <p>However, no matter what report I load, it displays as follows:</p>
  
  <p><img src="https://i.stack.imgur.com/rbDVr.png" alt="This is how it displays"></p>
  
  <p>When I use the exact same logic in a WinForms app to populate a CrystalReportsViewer there, the report displays as expected.</p>
  
  <p>Please advise as to what I am missing in the asp.net web form to make the report display correctly.</p>
