    Hi,

    We are using Telerik grids in our website built on ASP.Net 4.0. We are getting an internal exception as:

    System.Web.HttpException (0x80004005): This is an invalid webresource request.
       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)}

    This exception is thrown every time any grid loads. Though, this is not affecting grid's working but we want to track at which point this exception is thrown and how much this can affect our website's performace.

    Please help us regarding this.

    When I try to click the link in the thread provided it gives me a server error:

    "It seems there was a problem with our server."

    I, too, am having the same issue with the webresource request errors.  No users are reporting any errors but my error log is full of these.   This happened after an update to the telerik controls.  (now using the latest)

    Hello Bryan,

    The link should be working as expected now, sorry for the inconvenience. You could try decrypting the url to see the resource that is causing the problem. For more info, examine the following blog post:

    We've got this same error as well.  As many as 50+ / day are being reported.  I have checked out the blog post and implmeneted the page on my server.

    http://app7.publicaster.com/WebResources.aspx

    Enter in r2n-_ZX6pPRQ28WaIHMHICKCdzGauBOGUxb5iTgn3bRlgxQNTQc19uqgVIxpFfBNuBd6V3ddJuMkSOfDLY2mDV_HDSCmlIwWS9y9JLwT8ERhor_FfeC--WW29jqHRgd8fR3sUspgrInUtPCUIhKaP_OodfEMKQ4GUa2WoLSbML72pmnC0 in the first textbox, and you'll see the result that comes back says:

    Every error that is reported has this same identical querystring value.

    pTelerik.Web.UI|Telerik.Web.UI.Skins.Common.FileExplorerToolbarSprites.png

    The one thing that i notice is that there is a leading "p" before the Telerik.Web.UI and i wonder if that is the source of the problem.  Currently using version 2011.2.712.40.

    Hi Mark,

    Please try setting the EnableEmbeddedBaseStylesheet property of the affected controls to false.
    I hope this helps.
