chart control

Hi
For various reasons my current application is constrained to run with session handeling off.

Is there any chart setting or other tricks to get the essential chart working in this environment?

Currently I get an session error as soon as I add the chart control. If i turn sessionstate on, the chart works, but it is not the solution in my case.

Thank you

Hi Tobias,

Thanks for your interest in Syncfusion products.

I have tested for this issue "Exception is thrown when ChartWebControl is used with SessionState is off" and I am unable to reproduce this issue. Could you please provide us with the error information which you are getting when adding ChartWebControl to the Form when SessionMode is off. So that it will be more helpful for us to analyze and provide you with a better solution at the earliest.

Please let me know if you need any other information. Thanks for your patience.

Manohari, thanks for your time.
I get the following exception..

HttpException (0x80004005): 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 \\ section in the application configuration.]

I start with an empty project and just add a ChartWebControl on it. I am using version 5.202.0.25 and VS 2005 (SP 1)..

The only change is a web.config where

Great to have this confirmed.
We have a current license and will upgrade our product eventually. Since there are a lot of other code dependencies, we cannot do this immediately.

Do you know of any simple workarounds in order to use the chart control prior to an upgrade? I know we can always turn the session on for the pages using the chart, but do we have any other options?
Thank you
