Hi,

Please, see this forum post discussing this problem. My suggestion would be to remove any ChartHttpHandler registration from web.config and then to register it using the Visual Studio smart tag as shown in this help topic (see #4).

This problem has been solved by adding some line in web.config.

Let say my path:
test.com/Checking/Ck/index.aspx

 I added that line in web.config.
  <location path="Checking/Controls/ChartImage.axd">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorization>
    </system.web>
  </location>

Hope such type of things help you in future.

I had the same problem, for IIS7 the Telerik HTTP Handlers that you have in

I solved the issue by adding ChartHttpHandler

<handlers><add name="ChartHandler" path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler" /></handlers>

<add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" />

and also i added

<telrik:RadChart UseSession="false">
