Hi,

Since I upgraded my solution to ASP.NET 4 (webforms) and to Telerik RadControls 2010.1.519.40, I keep getting the following exception every time there is a new request to the server:

    
            Exception ID:   0 
        
            From:   System.Web 
        
            Time of Error:  6/23/2010 6:42:06 PM 
        
            Exception Type: System.Web.HttpException 
        
            Exception Message:  This is an invalid webresource request. 
        
            Exception Source:   System.Web 
        
            Source: Path :/WebResource.axd - Raw Url :/WebResource.axd?d=ajTmsUGo059i8jVyULN6WJxyGEzDWeYyk5iXrJ-hlCbfDyKpxWCzGgr__HcHehjE45vAS9-jMMZQxEhj5WlSgsmmlvC8804M8q7f1ZWxcrM4ODuYtuHJilKNWiCjODeP0&t=634129147086009932 
        
            Stack Trace:       at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)

               at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

And here is how my web.config looks like just in case it can help:

Hi Radoslav,

I try to solve the problem with your links but the problem persist.
I found well from wish webresource. This is only for the RadAjaxLoadingPanel when I use a custom image.
Without the custom image I don't have the problem.
My definition is :

<telerik:RadAjaxLoadingPanel runat="server" ID="LoadingPanel1" Skin="">

<img src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Vista.Ajax.loading7.gif") %>'

alt="Loading..." style="border: 0; margin-top: 45px;" />

</telerik:RadAjaxLoadingPanel>

The error code is:

URL:

http://SERVER_XXXX/WebResource.axd?d=owYWMOXGqqDrbAuzZcEwheNmL6MS09Sma-lqItu5zvMt6R7oFgXG6UyxR4ntPu2I-nJVZoNVi3Je73xI650nAo4cyHpPzQ9PMtOkIh32S6nRBq6hi8IcEFwu5aR_wlRxEo3AVRVk1eSyZAzwE7zcuAzP2jFdmwf01Yq5_-rcwlE1&t=634212761360000000

REFERRER:

http://SERVER_XXXX/Pages/VacancyAddEdit.aspx

MESSAGE:

This is an invalid webresource request.

STACKTRACE:

at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)

at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()

at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I try to put the skin="" but without effect.
This problem is new for us since the new version of Telerik (Q2 2010) with .net4

Any idea to solve this please?

Regards,

Edwin.
