Hi,
I installed Telerik.Web.UI.dll in Gac and I set it in the machine's Web.config :
<handlers>
<add name="Telerik_Web_UI_WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />
</handlers>

as explained in http://www.telerik.com/help/aspnet-ajax/introduction-troubleshooting.html

Unfortunately, I have the following error.Does anyone know how to fix it?
Thank you.
Best regards,
Silvia

Hi Sebastian,
thank you for replying!
Actually we are not using the Disign in VS but only the Source. So, we don't have the Telerik.Web.Design.dll library installed in GAC but just the Telerik.Web.UI.dll. Moreover we checked to have Visual Studio 2008 SP1 installed.
Pratically, I followed these steps (as shown in http://www.telerik.com/help/aspnet-ajax/introduction-design-time-troubleshooting.html) :

GAC-deploy the control library assembly

Add Telerik.Web.UI.dll in the GAC (see details in this topic)
Remove Telerik.Web.UI.dll from your bin folder

Make sure you have the following line in your web.config:

Copyweb.config

<add assembly="Telerik.Web.UI, Version=2009.1.311.35, Culture=neutral, PublicKeyToken=121FAE78165BA3D4"/>

To be more precise I'll report the code in my machine's web.config sections below:

<assemblies>
... ... ...
<add assembly="Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121FAE78165BA3D4"/>
</assemblies>
<handlers>
... ... ...
<add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" verb="*" preCondition="integratedMode" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2009.2.826.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />
</handlers>
<httpHandlers>
.... ... ...
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
</httpHandlers>
<controls>
... ... ...
<add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
</controls>

And now I have the following problem:

Server Error in '/' Application.

'~/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

Do you find something wrong in my web.config sections? Do you have any other tips?
Thank you!
