    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.

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

    Is anyone experiencing the same problem? Any help will be greatly appreciated!

    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:
     
    REFERRER:
     
    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.
