RadControls for ASP.NET are no longer supported (see this page for reference). In case you have inquiries about the Telerik ASP.NET AJAX controls, post them in the pertinent ASP.NET AJAX forums.

    Hi

    I have a panelbar on my page. when the page loads first (without using explorer cache) there is an explorer acript error on the page- "RadPanelBar is undefined", and the panelbar doesnt load.

    After reloading the page and any other load after that the panel bar loads fine.


    any ideas?

    thank you

    Hi Asaf,

    Could you please open a support ticket and send us a simple running project (not just separate file or code snippet) that demonstrates the problem? We would be really glad if you try to isolate the problem as much as possible (no 3rd party controls). Once we review the project, we will be able to give you a proper solution.

    Kind regards,
    Paul

    I receive the same error.  On the original page load everything comes up fine, but on consecutive postbacks I will get this error.  It looks like somehow the reference to the internal js for the panelbar gets lost.

    This did not really help with anything.

    I too am having this issue.  The control renders fine at the initial load and continues to work fine during regular postbacks.  However, there are postbacks where we do a Server.Transfer back to the same page.  It is these that cause the error to occur.  I checked all the troubleshooting in the referenced post, but the webresource.axd file is accessible.  Any ideas?
