    I notice that none of the ASP.NET AJAX demos work in IE 10 on the Windows 8 developer preview, on both the desktop and the metro interfaces. Is there an easy fix for getting the demos to run? Does anyone else have this experience?

    Hi Tom,

    IE 10 breaks all ASP.NET WebForms based sites, not only on Windows8, but on Winndows7 as well. The reason for that lies within the framework (.NET) itself. You could read more about it here -- http://www.hanselman.com/blog/BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition.aspx.

    In addition, Windows8 is and IE10 are not production ready pieces of software and it is expected some things not to be working.

    We are always looking into new technologies and we are making sure that our products work with them. But until we have a stable release of IE10 and / or Windows8, say RTM or RC, we cannot really offer solutions for any quirks and bugs, as things might change in matter of days and even hours.

    Tom,

    In fairness to telerik, Steven Sinofsky did say, when he announced the developer previews, was that one of the things you could expect (from Microsoft) was no support!

    Not just you, but everybody, so even telerik, if they wanted to could only do so much to get things working right on this platform 'cos they couldn't get any help from MS with any problems they find with it.

    I know that telerik are committed to supporting this platform, as soon as they are able and you will prolly find that as the Win8/IE10 platforms mature on the road to General Release, telerik will be working hard to get their tools working for all.

    Thanks for the thorough response. The link is especially useful.
    As you and Stuart note, Win8 and IE10 are very beta-ish, and there is a long way to go before release.

    I'm glad to hear that Telerik is keeping an eye on it at least!

    Hi,

    I am trying to run the telerik controls in IE 10 standard mode on Windows 8 operating system. The RadGrid is not  rendering in the IE 10 Standard Mode.

    I am getting the error like this: SCRIPT5007: Unable to get value of the property 'PageRequestManager': object is null or undefined. 
    ScriptResource.axd, line 77 character 1

    But it renders only in the IE10 compatible mode.

    Looking forward for your reply.

    Thanks

    Hello Agsar,

    Do you reproduce the problem at our online demos?
    Our latest build - 2012.2.815.40 - is fully functional under IE10.

    Kind regards,

    Actually Windows 8 IS released now.  It has been released to MSDN subscribers as a final version.  When will this be updated?

    Hi, is this issue fixed on the latest version Q3 2012? I still get the following error using IE10:
    SCRIPT5007: Unable to get property 'PageRequestManager' of undefined or null reference
    Telerik.Web.UI.WebResource.axd, line 4566 character 1
    Which result in a lot of things broke, such as the $find(...) returns null.
    However, if I change the browser mode to IE10 compatibility mode, it works properly.

    Any idea how we can solve this or any settings we were missing?
    Thanks

    So here's what I did to fix:  normally if you're using Visual Studio to "Publish" to a site folder, beware that the binaries for the telerik DLL's (the UPDATED versions of them) are being copied over.  I went to MY latest version which was here:

    C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q2 2012 SP2

    And then chose either the Bin35 or the Bin40 (depending upon which build of .NET you've coded to) and make sure THOSE dll's are in your project as the references.  When you either do a PUBLISH or copy over, MAKE SURE these new versions copied over.

    That fixed my problem.  Hope it fixes yours.

    Thank you for your reply. I am actually using newer version now: RadControls for ASP.NET AJAX Q3 2012. I will try downgrade to the older version and see if it works.

    Make no mistake - I'm not necessarily saying to downgrade.  What I'm saying is, if you're having the same problem that I had, you'll notice that it WORKS in dev, and NOT on server.  Is that the case?  If so, check the BIN directory on your web solution on the SERVER and check which version the telerik DLL's are.

    OK. I was thinking the version of telerik control might result in different result, but it's not. I did checked and confirmed that the proper dll is copied over to the server. My bad, I originally only tested IE10 on testing environment but not the dev environment, Checked again, it actually works on dev but not on our testing environment. According to one of the post in the forum, I am trying turning off the HTTP compression on our testing environment and see whether it will work.

    Thanks. I was focusing on other tasks and didn't got the time to get back to this issue till now, I just checked, the compression is off on our testing environment now, but still not working. 

    Our development environment using IIS7 but our testing and deployment environment currently using IIS6, Due to some history issue, we probably won't be able to change to IIS7 on testing and deployment environment soon, just wonder anything might went wrong? It works before

    On IIS if you want to turn off compression for everything, find the server tab from the websites, and you can turn on/off the compression from there.
