Hi Telerik,
I have been used Telerik RadChart Q1 2010 on SharePoint 2007 successfully. But, now I use Telerik RadChart Q1 2010 on SharePoint 2010, I get the following error message
The ... Web Part appears to be causing a problem. Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.
I modified my web.config as what the error say, but it doesn't help. Here is my web.config:

<httpHandlers>
<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2010.1.415.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

I render the RadChart directly on the Page, It means Page.Controls.Add(radChart). I know I can render RadChart's Image, but it doesn't meet my requirement
So, anybody please help me to solve this problem
Thanks
