Hi Dave1,

We discovered recently some limitations in RadScriptManager, happening after the install of .NET Framework 3.5 SP1. Can you please, help us identify if you face the same? Are you registering some ScriptReferences to the <Scripts> property of RadScriptManager?

Can you send us your page (a formal support ticket will allow the file attachment and will keep it private).

I have a small project that consistenly demonstrates this issue--how do I send it to you?

[Sebastian]

Hi Dave1,

You can start a regular support ticket from your Client.NET account and submit the sample project attached to it (along with a short description). Thus we will be able to test/debug it locally and advice you further.

Has this issue been resolved?

[Sebastian]

Hi John,

The issue reported here should be addressed in the latest version 2008.3.1125 of RadControls for ASP.NET AJAX.

Note that this error can also be generated when you have not granted permissions tfor the Telerik.Web.UI.WebResource.axd http handler to all users (through the web.config file). Review the relevant section of this help topic for more details.

Help me!
Thanks

Hi Antonello,

Review the communication in this forum post and upgrade your AJAX controls to more recent version as the one you are using is quite old now (dating almost 4 years ago). Thus you should be able to eliminate any incompatibility issues between our controls and the MS AJAX toolkit.

Hi,

I would not go to AjaxControlToolkit 4.0.... because my application is compiled with framework 3.5 and I used the other components that would not work.
Is there a solution for my problem with my components ajax vs telerik?
But If I used ajaxcontroltoolkit 3.5.40412.0, framework 3.5 and I updated dll telerik from 2008 in 2010; can i resolved my problem?

Thank you

[Sebastian]

Hi Antonello,

Can you verify that you are using the .NET 35 2010 version of our AJAX controls along with the AJAX toolkit .NET 35 version? This should help you use both side by side, although to ensure that all compatibility issues will be eliminated, we recommend using the most recent version of our AJAX components.

Hi,

I used in my application AjaxToolkit 3.5.50972.0 (version of 35), but i used the version telerik.web.ui.dll 2008.1.515.20
The problem may be because the version of telerik but is the last version we fired.

Thank you.

My problem was the incorrect version in web.config for the WebResource.axd handler.  It neede to be the latest version:

<handlers>
      <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2013.1.220.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
         name="Telerik.Web.UI.WebResource"/>
    </handlers>
