    I'm working on an asp.net project where i have a master page and content pages. Im getting an exception message when i place a timer on one of the content page which is ticking at a certain interval and rebinding the grid using rebind method. I have got  a RadScripManager placed on my master page. Im also using radajaxmanager for the timer.

    Please, make sure that the IE11 browser is not running in Compatibility mode as it is not supported and may lead to such issues:

    Also, you stated that you are using the latest version of the controls (2017.2.621), but the thrown error indicates a reference to version 2016.2.607.45. Can you please, make sure that there are not any remaining references in you project pointing to this version? I would also advise that you also check the *.proj file of the application by opening it in a text redactor (i.e., NotePad++) and search for any remaining references to the 2016 version of the controls there.

    The following blog posts provides detailed steps on how to successfully upgrade a project, you may find it useful:

    If non of the above helps, please, send us a runnable simple project where the problem can be replicated, so we can examine the cause for it further at our end.
