I to am getting the same error.

I have a basic page, within a master page, a web control and the rad scheduler.

Dave,

I fixed my problem by adding code to my web.config file. I looked into the examples that Telerik provides for Prometheus. I ran the solution, and it worked. So that told me that it was not a problem with my box.

I looked at the web.config file in the examples, and noticed a lot of code that was not in mine. So bascialy I copied that parts mine did not contain that applied only to the script manager, and the scheduler. I obviously didnt copy over any appsettings or connection strings. And that seemed to work for me....

Here is what my web.config file looks like now...

I have one... I build my pages dynamically in the Page_Init routine - which loads the modules dynamically. I can only guess that the error occurs because something does not get written at the correct time during the generation of the page but have checked and all the html seems in order.

I have come to a dead-end trying to figure this out and it is the only thing I can come up with. I also create the ScriptManager on the page dynamically during the Page_Init routine. I have used other vendors controls supporting Microsoft Ajax and they work with my method - but prefer Telerik's codebase - actually I wish I could just use Telerik's Ajax - but prometheus seems to be the roadmap.

hope this helps narrow it down some.

Hello David,

After inspecting your site I found out that requesting http://84.65.125.118:8083/McDiamonds/Telerik.Web.UI.WebResource.axd returns 404 for some reason.

This URL is rendered by RadScriptManager and represents the http handler serving JavaScript resources. The 404 error is effectively causing the "Telerik is undefined" error because no telerik scripts have been loaded. It also appears that some other HTTP handler ThumbHandler.ashx also returns 404. I have attached a screenshot from FireBug. It seems to me that http handlers do not work for some reason despite they are registered in the web.config. Maybe it's because you are web application is running in Integrated mode (IIS7).
You can try inserting the http handler registration inside <system.webServer> instead of <system.web>:

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

I hope this helps,

I ran into this problem as well - ends up it was because authentication on the rest of the site - placing the following in my web config fixed it up:

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

Hello guyes.... I know this i an old post, but i just wanted to add a comment on why this problems can occour when you upgrade to the new IIS 7.0.

I was running my site on IIS 6 and everything worked fine. But after installing Windows Server 2008 and thereby also IIS 7 i got this problem.

I found out that my problem was caused by how the application pools act in IIS 7 by default.

An application pool is set to run "Integrated" managed pipeline Mode. This causes this error to. From IIs manager you must switch over to Classic managed pipeline mode to get the telerik radmenu to work again!

Hope this might help somebody if they encounter same problem as i did!

Please note that it is better to get your app running in integrated mode than to switch it back to classic mode (you can configure your app to do so much more such as applying ASP.NET forms authentication to non-asp.net requests like static files, classic ASP files, etc).

To do so you just need to add the Telerik handlers to the <handlers> section of <system.webserver>, give them a 'name' attribute (it doesn't matter what), remove the 'validate="false"' attribute and add a preCondition="integratedMode" attribute. You will need to do this for at least the webresource handler and if you use the telerik editor, also the spellcheckhandler and dialoghandler.

e.g. you end up with

    
              <system.webServer> 
        
                <validation validateIntegratedModeConfiguration="false"/>

                </modules>

                </handlers> 
        
              </system.webServer>

where the last three items are the handlers you have to add, the rest having been automatically added by Telerik (I don't know why the last three are not auto added!).

I had the same "telerik undefined" script error, using version 2008.2.723.35. After searching for a very longtime I found a radmultipage wich had the EnableEmbeddedScripts set to false. To prove my manager that was the only error causing the javascript error I built a simplewebsite containing 1 page.

Maybe it saves someone time searching for a solution.

Hi Rolus,

By default JavaScript files are served as web resources (embedded in the Telerik.Web.UI.dll assembly).

For custom deployment scenarios you can specify an alternative location for JavaScript files. To do so you should set the EnableEmbeddedScripts property to false. Then, the JavaScript files will not be loaded from the assembly.

You will also need to add a script reference for each JavaScript file through the ScriptManager or RadScriptManager.

A list of the JavaScript files used by RadMultiPage for ASP.NET AJAX can be found below. You need to register only the JavaScript files required by the controls you are currently using. Common JavaScript files (e.g. Core.js) should be registered only once.

    
             <telerik:RadScriptManager ID="RadScriptManager1" runat="server">  
        
                <Scripts> 
        
                    <asp:ScriptReference Path="~/Scripts/Common/Core.js" /> 
        
                    <asp:ScriptReference Path="~/Scripts/TabStrip/MultiPage/RadMultiPageScripts.js" /> 
        
                </Scripts> 
        
            </telerik:RadScriptManager>

All JavaScript files are available in the distribution (EXE, ZIP and hotfix) of RadControls' "Scripts" folder.

Note that the order of the js files registered for most of RadControls is important since there are some dependencies between the javascript files of a single control. Therefore it is recommended to follow the exact order of the script references from the table below.

All the best,

I had a strange problem with users who must use Windows 2000 and IE6. I wrote a web part that can create a control with multiple tab, multiple page, and multiple grid objects. The web part can be bound to a SQL database tables and allows the user to perform CRUD (create, retrieve, update, and delete) operations.

The web part works great on my test machine; which is a virtual machine with Windows 2003 Server, SQL Server 2005 and SharePoint 2007. When I deploy the web part to my production SharePoint server, it also works greate with my Windows XP operating system and IE6. (I know most of the software I mention is older, but not all corporations have moved to Vista.)

Some of my users who have Windows 2000 were getting the error "Telerik is undefined" after navigating to the page that had the web part deployed on the page. Not all of them, but enough to be problematic. Those users that were having the problem, it was found that if they go to TOOLS --> INTERNET OPTIONS --> GENERAL tab and click the "Delete Files" under the Temporary Internet Files section, close down all browsers, open a browser and navigate back to the same page, the tabs, the grids, command item templates, and paging all work every time. But how can you require that a user perform this action every time they navigate to the page? Well, the answer is "you can't and shouldn't".

Luckly, I have some bright users who enjoy tinkering. One of them who was helping me test, clicked on the menu TOOLS --> INTERNET OPTIONS --> ADVANCED tab and just started reading all the options that were available on the ADVANCED tab. He found one named "Do not save encrypted pages to disk". He checked it, closed the browser, restarted a browser session, navigated to the page with the web part and it worked. He closed the browser and navigated several more times to the page and it worked. He found the problem.

Now the funny part, my browser had the option unchecked and it worked every time. The difference is I am using Windows XP and he is using Windows 2000. We are both using IE6. Apparently the browsers handle encrypted pages differently. I should mention, that I discovered, by looking at the HTML source, that not all of the page was encrypted, just certain parts (I assume which are javascript for the Telerik product). Because a certain part of the page is encrypted, I cannot tell what it is doing or what generated it. But it must be cached and used the next time the user tries to open the page.

Anyway, what solved my problem. Just check this option "Do not save encrypted pages to disk" on Windows 2000 workstations, and the "Telerik is undefined" error goes away.

By the way, I am using the 2008.1.515.35 version of the grid.
