    When spell checking any rich formatted text, I keep receiving the following error:

    A potentially dangerous Request.Form value was detected from the client (CommandArgument="s<teleriklf /><teleri...").

    I added the following to web.config, but it does not solve the problem:

    <location path="Telerik.Web.UI.SpellCheckHandler.axd">

        <system.web>

            <pages validateRequest="false"></pages>

        </system.web>

    </location>

    Any ideas?

    Hello,

    I assume that you are using .NET 4.0. If this is the case, please update to the latest ASP.NET AJAX release (2010.1.415). This problem has already been reported and fixed in the current release.

    Yes, ASP.NET 4.0.

    That fixed the problem.

    Thank You,

    Hi,

    If you are using ASP.NET 4.0, then you can refer to the following document for a fix - http://www.asp.net/learn/whitepapers/aspnet4/breaking-changes#0.1__Toc256770147

    You need to add the following line in your web.config file:

    <httpRuntime requestValidationMode="2.0" />

    Hi Lini thanks for the help,

    I currently have <httpRuntime requestValidationMode="2.0" /> in my web config, and have tried all the other suggestions that were mentioned in the link that you replied with, but still the error occurs.  Any advice?

    Hi Pat,

    There is another forum which offers a solution for this error. Here it is:
    500 error when spell checking.

    If you unable to fix it, open a support ticket and provide a sample working project which demonstrates the problem.
