    I've upgraded the web site to framework 4 and Telerik ASP.NET Ajax Controls 2013 Q1 (also tried 2012 Q3) framework 4.0.
    It's Windows Server 2008, IIS 7,
    Application Pool is .NET fr. 4.0.30319, Integrated mode, Local System account

    Telerik Controls do not respond on click events.
    RadTabStrip, RadComboBox, RadMenu, RadToolbar

    Can see JS error in Web developer tools:
    Uncaught ReferenceError: Sys is not defined Uncaught ReferenceError: Telerik is not defined
    and many of those:
    Failed to load resource: the server responded with a status of 404 (Not Found) ....

    web config sections:
       <add name="Telerik_Web_UI_WebResource_axd" preCondition="integratedMode"
           path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource"
           verb="*" />
      <remove name="RadCompression"/>
    name="RadCompression" type="Telerik.Web.UI.RadCompression" />
    <pages enableViewStateMac="false"
    assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagPrefix="telerik"/>

    ok, found it, i was using asp ScriptManager on the master which was not registered in web config 
    the solution is or register it or use the Telerik Rad.ScriptManager

    Hello Oksana,

    The exception that you are getting indicates that any of the scripts needed for the RadControls to work properly does not get loaded on the page. Please refer to the following help articles where you can find more detailed information on how to resolve the exceptions that you get:

    My solution was to remove "runtimeVersionv2.0" from
    <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/>
