    Hi

    We noted an issue with our "dashboard" website (a portal for our clients to query data and view charts etc.). The issue was that the RadControl styling seemed not to work and the controls were not responding to user input in the newly released IE11 only. 

    The Telerik ASP.NET AJAX controls were upgraded from the Q3-2012 version to the Q3-2013 version the problem seems to have been fixed in dev but when published to the test server (identical to the live environment) the issue still exists with IE11 returning a JS error:

    in Telerik.Web.UI.WebResource.axd:
    line 6418 - window[Sys.WebForms.PageRequestManager.getInstance()._uniqueIDToClientID(this._uniqueID)]=this;
    Unable to get property 'PageRequestManager' of undefined or null reference 

    NB: I did not originally discover these faults and have been drafted in to perform the Telerik component upgrade only but now I must see the issue through to the end.

    I believe that this is either an issue with the Telerik Component or .NET Framework or IE11.

    Your help is appreciated

    Hi Tim,

    This is a problem in .NET 4. This sticky thread explains it: http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/incorrectly-rendered-webpage-when-using-internet-explorer-11.aspx.

    Hi,

    just to make sure, does the mentioned patch need to be installed on the server or on every client accessing the website?

    TIA

    Hi, Martin.

    The patch needs to be installed only on the server(s).
