Error loading ChartImage

[Divyesh]

I get "Error loading RadChart image." error when i browse a page that has chart control in it. This is trial version and i am middle of evaluating the product on widows xp. I search through forum here but that did not solve my issue because i do not have session tag in web.confg. I gave aspnet user full control on site to see if this is a permission issue.
Version: 2008.2 723 Released:7/23/2008

Here is sample code:

<

telerik:RadChart ID="radChartByModelCode" Width="900px" Height="500px" Skin="Web20" runat="server"></telerik:RadChart>

I also tried setting UserSession="false" but same error.

I did ran into those threads and tried out their suggestions.
Still I get same error.

"error loading RadChart image" and "App_GlobalResources"

UserSession="false"

Hello Divyesh,

The only known reason for such error is incorrectly registered http handler. Does the issue appear in a brand new web site with a single page with RadChart in it? Did you try to register the http handler from the chart smart tag as shown here? You you still experience the same problem, can you send this web-site to us, so we can review it? Thanks.

Note, that the property is UseSession. Still, this does not seem to be relevant in this case, as the property remains with its default value - true.

Sincerely,

I had the same issue in a site with forms authentication enabled and one
non-secured page with a chart control. To solve this i've added the following lines to the locations web.config section:

  <location path="ChartImage.axd">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorization>
    </system.web>
  </location>

in order to don't block the non authenticated calls to the chart handler.

Hope that this helps.

Hi,

I am having the same problem and tried all the workarounds suggested but still the error persists. The RadChart is located on the same page as the data entry page where it is initially hidden from view until the user submits the page. The whole application (where the RadChart control is used) is hosted inside an iframe from a different web application/domain.

Thanks,

Ely
