Hi talha,

Please, check the "Integrating RadControls in Sharepoint" section of our online help. In addition, here are some general hints about RadChart -- make sure the chart httphandler is correctly registered in your moss site web.config file. In this page you can find details about extending your moss site with MS ASP.NET AJAX. In a similar manner, you need to add this line to the <httphandlers> section:

<add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/>

RadChart uses an additional namespace -- Telerik.Charting, you may need to add an additional tag in the safe controls section.

In addition, RadChart needs the SessionState by default. If you have disabled it - you may configure RadChart not to use it. You can find more details here.

Finally, you can check this forum thread, discussing RadChart and MOSS. Hope this helps.

Greetings,
Ves
