Update messed up my project!!!

[Duncan]

I just ran the Telerik update wizard because for some reason my web.config was not setup to run RadControls. It modified my web.config. I am not getting the following error:

ASP.NET Ajax client-side framework failed to load.

What is going on? Can someone please help me unscrew my project...

Thanks,
Duncan

If i revert my web.config back to the backup i get this error:

'~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: '~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadScriptManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadScriptManager

If i refrain from using the RadScriptManager and revert back to using a normal ScriptManager, my project works fine. Except on some pages when i operation is performed i receive the following error:

Sys.InvalidOperationException: A control is already associated with the element.

The above error what why i attempted to us the RadScriptManager in the first place...

Any help would be welcome!!

[Duncan]

Can anyone give me any assistance as to why my project is reacting in this way?

Hello Duncan,

If RadScriptManager is deployed and you get the missing handler exception, please open a page with the control in VS Designer, click on the control's designer, open its smart tag and choose the register Telerik.Web.UI.WebResource.axd handler in web.config.

After the registration process finishes you should be able to run your pages without problems. Please let me know how it goes.

Best wishes,

Hi Simon,

I added the RadScriptManager back to my project and registered it as you suggested. When i do this i recieve the following error:

Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load.

Am i missing something?

Hi Duncan,

There may be various reasons for this error. Could you please let me know whether you have authentication enabled in your project?

Kind regards,

Yes i do:

<authentication mode="Forms">
  <forms cookieless="AutoDetect" slidingExpiration="true" loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
  </forms>
</authentication>

I'm running the following:

• Framework 4.0
• Windows 7
• IIS 7
• RadControls v.2011.2.915.40 (Trial) - I plan on a full version purchase if i can get this issue fixed

Here is my full web.config file, minus the sensitive parts:

Please let me know if you need any more details...

Hello Duncan,

Thank you for this info.

The error you are seeing after you configured RadScriptManager to work properly most commonly arises if web forms authentication is used. More specifically in this way access to the Telerik.Web.UI.WebResource.axd handler serving all the scripts and style sheets is denied. You need to explicitly allow access to the handler in your web.config.

web.config

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

A bit more info about the problem you could find here.

I hope this helps.

All the best,
Simon

Thanks Simon,

That seems to do the trick...
