title: asp chart errors
body: <p>I have a strange situation using asp ajax chart controls.  I have an application which is attempting to display a chart on an aspx page.  Here are a couple of snippets from my web.config - </p>
  
  <pre><code>&lt;appSettings&gt;
      &lt;add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\temp\;"/&gt;
  &lt;/appSettings&gt;
  </code></pre>
  
  <p>...</p>
  
  <pre><code>&lt;httpHandlers&gt;
      &lt;add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/&gt;
  &lt;/httpHandlers&gt;
  </code></pre>
  
  <p>...</p>
  
  <pre><code>&lt;handlers&gt;
      &lt;remove name="ChartImageHandler"/&gt;
      &lt;add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/&gt;
  &lt;/handlers&gt;
  </code></pre>
  
  <p>When I run the application through the VS2010 IDE, I am getting the following error when trying to display the chart - </p>
  
  <pre><code>Parser Error 
  Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. 
  
  Parser Error Message: Unknown server tag 'asp:Chart'.
  </code></pre>
  
  <p>However, if I deploy it to my server, it seems that the chart cannot be found (an outline where the image would be appears with the red X saying that the image cannot be found).
  The difference is that I am running the IDE from windows xp 32bit machine, and the server I deploy to is a 64bit Server 2008 machine running IIS 7.</p>
  
  <p>Does anyone have any idea why I might be having these problems?
  Thanks for any thoughts.</p>
