title: Telerik Reporting | Set Report Parameter Via Query String
body: <p><strong>Problem:</strong>
  I am trying to pass a Report Parameter value from the query string on the page to my report that already has the parameter defined.  I just can't seem to get the value passed all the way to the report.  </p>
  
  <pre><code>        Telerik.Reporting.Report report = new MyCustomReportLibrary.TelerikReport();
          report.ReportParameters["parameterName"].Value = Request.QueryString["Id"];
  
          ReportViewer.Report = report;
  </code></pre>
  
  <p>This syntax above is fine but when the variable <strong>"report"</strong> is created by the <strong>TelerikReport()</strong> constructor it doesn't have a value for the parameter yet and when I set it after the fact it doesn't seem to matter.  Even if I try to call a <strong>ReportViewer.RefreshReport()</strong>.  </p>
  
  <p><strong>Places I have looked:</strong></p>

  <li>I also submitted a telerik support ticket but tomorrow is Bulgarian Independence day.</li>
  </ul>
  
  <p>Thanks for the help,</p>
