  Hi,
  
  I have been trying to use RadChart but the handler just fails to register. Here is the error message when the chart tried to display on the page.
  
  The Chart http handler is not registered. Please, manually add the following line to your Web.config httpHandlers section:
  <add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2010.3.1317.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
  
  I have modified my web.config file according to the instruction specified at http://www.telerik.com/help/aspnet-ajax/registering_the_httphandlers_on_windows_vista_iis_7_integrated_mode.html.
  
  Here is my current web.config file.
  
  

  <?xml version="1.0"?>

         preCondition="integratedMode" />

      </handlers>

    </system.webServer>

  </configuration>

  
  Any suggestion?

  Hi Surya,
  
  The easiest solution would be to clean all chart related entries from your web.config file and use the control smart tag to re-create the chart handler registration.
