    We are using controls suite called "Prometheus"... when we placed on a page a RadCombobox and loaded the page, an error was shown telling that ScriptManager must be present.

    When we added ScriptManager to the page, a JavaScript error was shown, telling that 'Sys' in undefined.

    How to solve it? why RadCombobox depends on ScriptManager presence in the page?

    Thanks in advance

    Hey Jaime,

    Just checking, did you click on the smart tag on the ScriptManager to register it?  I always forget to do that and it often causes trouble for me. ;D

    Otherwise, be sure that you have the Register item towards the top of the aspx for Telerik.Web.UI and that your web.config has been properly updated with the Telerik handlers. 

    You can also check out this thread, contains a lot of discussion regarding Telerik controls, the AJAX toolkit, and fixing the Sys error.
