  System.UnauthorizedAccessException (Chart Control)

  May 08, 2012 04:59 AM|LINK

  I had used Microsoft chart control and in my local server it is working fine but in thirdparty webserver i am getting below error,

  How to overcome this error ??

  The temp directory in chart handler configuration is not accessible [D:/webdata/abc.com/TempFiles]

  Exception Details: System.UnauthorizedAccessException: The temp directory in chart handler configuration is not accessible

  My code is:
  
  <handlers>
  <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"/>
  </handlers>
  
  <httpHandlers>
  <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"/>
  </httpHandlers>
  
  <appSettings>
  <add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/TempFiles/;"/>
  </appSettings>

  Eventhough the Write permission was given to TempFiles folder,Getting error.

  Hence after R&D, came to conclusion that the Storage was used Memory and deleteAfterServicing=true attributes resolved the issue.

  Solution:

  <add key="ChartImageHandler" value="storage=memory;deleteAfterServicing=true;timeout=20;"/>
