    Hi,

    I have made a webpart for sharepoint that uses the radchart. The radchart appears in the webpart but has message to add following to my web.config:
    <add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

    When I add the above line, I start getting the following error. If I remove the line, the error goes away

    Server Error in '/' Application.


    Unable to connect to SQL Server session database. The connection string (server='xxxxxxxxx', database='SharedServices_DB') was returned by an instance of the IPartitionResolver type 'Microsoft.Office.Server.Administration.SqlSessionStateResolver, Microsoft.Office.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.

    Hello Kunal,

    The error does not seem to be directly related to RadChart, but rather to the fact that it uses the session state. You can test this by removing RadChart from the page and adding some code that makes use of the session state. Fortunately, RadChart can run without session state, you can find more details here.
