    I am attempting to get the RadSpell control from the Q1 2016 release to work in my project, but thus far I keep getting a 404 error when clicking on the button. I used the smart tag for the RadSpell to add the appropriate HttpHandlers and what-not:


                <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />
                <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" />
                <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
                <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" />
                <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />

    as well as the following to my web.config file:

    <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" />
    <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode" />
    <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" />
    <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode" />
    <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" />

    However, every time I try to click the button I get a 404 for the following RequestUrl:


    I can't for the life of me figure out what I've done wrong. I know it has to be some configuration issue, because I can create a Telerik Web Forms app and drop the RadSpell control, click it and it works fine.

    Thanks in advance for any help.

    As I noted in my original post, I was having an issue getting the spell check dialog to work in my ASP.NET project, but it works fine in a Telerik ASP.NET Web Forms project. I have since tested this in a newly created and essentially empty (other than what VS creates for me) ASP.NET Web Forms project using the 4.5.2 Framework and Individual User Account authentication (the OWIN stuff). I simply added a RadTextBox and RadSpell controls to the Contact page and used the smart tag on the RadSpell to generate the HttpHandlers which it does. However, when I run this new project and click the RadSpell button I get the same 404 error as I get in my project.

    So, this is not something limited to my project per se: rather it seems to be an issue with a configuration difference between an ASP.NET Web Forms project vs a Telerik ASP.NET Web Forms project.

    Any help or guidance here would be greatly appreciated.

    P.S. If necessary I can attach the newly created ASP.NET solution or project source to help speed this process along if it's needed.

    Hello Travis,

    I have already replied to the support ticket that was opened by you on the matter, so that I paste my answer as follows:

    I would suggest that you try the following:
         - Ensure you have followed the steps for configure the spell from this article - http://docs.telerik.com/devtools/aspnet-ajax/controls/spell/getting-started
         - See how the spell and the webresource handlers should look like here - http://docs.telerik.com/devtools/aspnet-ajax/general-information/web-config-settings-overview#mandatory-additions-to-the-webconfig
         - The following article treats the "404  error code" issue  - http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/web-resources-troubleshooting#dealing-with-the-404-error-code-the-requested-url-was-not-found
          - Examine this forum post (http://www.telerik.com/forums/radspell-web-config-404-error#xquGbOZ4aUSY_07LCbuuew) that treats the exact issue with the spell.

    If the information from the above resource doesn't help it would be better to reproduce the issue in a runnable sample and then provide it back to us, so that we can proceed further with the investigation.
