Rad chart control giving exception

[kiran]

HI,

I have used rad chart control in ascx control of sitefinity application.

For that i have added below code to the ascx control

<telerik:RadChart ID="RadChart2" runat="server">
     <Series>
         <telerik:ChartSeries>
             <Items>
                 <telerik:ChartSeriesItem YValue="10" />
                 <telerik:ChartSeriesItem YValue="15" />
             </Items>
         </telerik:ChartSeries>
     </Series>
 </telerik:RadChart>

 

and added below tags to the web.config file.

Below are added to the controls of pages tag.

<add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
 <add tagPrefix="telerik" namespace="Telerik.Charting" assembly="Telerik.Web.UI"/>

 

And the below tag has been added to httpHandlers section of system.web.

<add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" verb="*" validate="false"/>

 

And another tag has been added to handlers section of system.webserver

<add name="ChartImage_axd" verb="*" preCondition="integratedMode" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>

 

But I am getting the following exception when accessing the corresponding page.

“Error loading RadChart image.You may also wish to check the ASP.NET Trace for further details.Display stack trace?”

I am using iis 7.5.Please suggest me how to solve this issue.

 

 Thanks
Kiran G.

Hello Kiran,

It is possible that there is an issue with the handler that processes the image of the chart control - ChartImage.axd, so you can try to explicitly add reference as shown in the code sample below

RadChart1.HttpHandlerUrl = ResolveUrl("ChartImage.axd");

Greetings,
Bart.
