Hi all,

we build a very simple scrolling-example (using codecharge studio 4.1) but we get always the following server error message. All other telerik asp.net ajax applications and functions (charts, editor, combo boxes ...) we tested makes no problems (congratulation on the very good work of developers!). But after insert the <clientsettings .../> row in the code we get this error message. We use Windows xp / windows 2003 server and asp.net latest versions, IE7 and firefox latest versions, 2008Q3 trial latest build ... The problem is independent from windows, browser etc.

Has anybody an idea? Is this a bug?

thanks for help.
Regards Christian

Hello Chris,

Unfortunately, CodeCharge studio is not in our supported development tools list. Can you please verify if the error appears when using Visual Studio? In this case, please send us the page so we can review it locally and provide further assistance. Thanks.

All the best,

Hello Suketu,

I tested the sutup, and the control behaved as expected. Attached to this message, you will find the code, which I used for testing. Give it a try, and let me know whether you are able to replicate the exception reported earlier.
