    We have just started using UI for ASP.NET AJAX. Everything works fine until we try using client-side code. We keep receiving this error : "JavaScript runtime error : '$telerik' is undefined". I've searched for a solution online but none of the suggested solutions works.


    At the moment our web.config has the following entries which according to online sources would solve the problem but didn't :

     <location path="Telerik.Web.UI.WebResource.axd">
          <allow users="*"/>

        <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />        

        <add name="Telerik.Web.UI.WebResource"  path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2014.2.724.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />

     We also tried the following to no avail :

        <add name="Telerik_Web_UI_WebResource_axd" verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" preCondition="integratedMode" />

    In default.aspx we have the following :


            <telerik:RadScriptManager ID="scriptManagerMain" runat="server">
                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
                    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
                    <asp:ServiceReference Path="~/WCF/DataService.svc"/>
            <telerik:RadAjaxManager ID="radAjaxManagerMain" runat="server">

    With all these settings we still keep receiving the "JavaScript runtime error : '$telerik' is undefined" error.​ I really hope someone knows the solution to this problem because we're stick here and can't find a solution. Thanks in advance for any help.
