title: Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form
body: <p>I'm having a bit of an issue with the ReportViewer module in C#.</p>
  
  <p>I've added in the report to my website using the instructions provided here: <a href="https://msdn.microsoft.com/en-us/library/ms252123(v=vs.90).aspx" rel="nofollow">MSDN</a>. It uses the design viewer aspect of visual studio which is horrible to use and seems to have left me without some code I need to get it working.</p>
  
  <p>I am getting this error when I try to load the page:</p>
  
  <p>The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form.</p>
  
  <p>The code added to the page by ReportViewer seems to be (I can't find any other references to ReportViewer):</p>
  
  <pre><code>            &lt;rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt"&gt;
              &lt;LocalReport ReportPath="Pages\Report1.rdlc"&gt;
              &lt;/LocalReport&gt;
          &lt;/rsweb:ReportViewer&gt;
  </code></pre>
  
  <p>I feel like I'm missing a large amount of code to configure ReportViewer but I can't work out what I'm missing.</p>
  
  <p>I've had a good search for what but couldn't find out what.</p>
  
  <p>Thanks for the help in advance</p>
