404 Not found error

[Travis]

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:

 

<httpHandlers>
            <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" />
    </httpHandlers>

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

<handlers>
<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" />
</handlers>

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

http://localhost:59087/Telerik.Web.UI.DialogHandler?DialogName=SpellCheckDialog&renderMode=2&Skin=Default&Title=&doid=48aede83-f455-4bde-a8ff-57a75e51bcbe&dpptn=&dp=dwkeUFUDGy9nFThMLRwMTlEnAjcgARF2bU8WVEZqVn4keTgQF38eXRMxD3cnZENrRH98G2h3QWJlBiBkKxwYTld6AiUfEhF2VBEeUkF6Vn4keTgQF38eUBMyJVgmdH4Gcn0OX2t3dDNvYAFVGzYmS1B4ET0IFChwZXUeVEdsfEkeHRICL0EnRhMxLUkga2Vdan4NWXwQVh5UBRoWKAxZTWoSDnsREBkybREaTHkbe0ovQwYZLh48WRI3D0AUWXkBcFYSZGEQVh1XPxJPKxw2flEdDiIfEA0rbWQCVkJ%2BG0MxaxoCL2QnRhMwOlIUa2EAfG48flIDdChXFxpJEwwuSmYCDjghOjMsbXoGcUZxbFUpQwYeF38RbQYjD1sYcFxGan48bVIpZDVXBQJTLR4MVlEnfTcfAmYwU2UgUkFHY0ovQwYZLh48WRIdABINEmFdRFcaRlIvEy1vFQFVGzYmS1B4ET0IPig%2BeBI0UnobaEocdjACKWsFXD0YNUkmZExCdFcOWVJ2dyh4ESMRGAwQUFYMEjcnFCcAbnU0Xnl6WU4xazcSGEERQw1FLRQbdU9LQmwRU2cpThZXFA5tHRwYd1d7NBYgHxEVek8kV3R9ZAkueCwyA3sdQw1FLRQWZBp2aHw4aGEQEmxjYG1fEx4MVlEnfTcfAmYwU2UgUkFHY0ovQwYZLh48WRIdABENE31Ef20CWWsRdC9sPwJNExw2U2Z4CjckDx13VFs0Y3p%2BVkMnfTcQAWo7UzsjIhYQdB5Zf1cwRmMTEzJvBQZNEwwye2oSCiIQZA1yVWUaXkJueFUZbTgtFHsRUAUnAFsOZXlIQm0dHWB3dCFRFW1SGxwMUlcNKDgnOhk%2BUnQCUkdxZFMneBJfLms%2FZQYjRk0OZnFZRHIGRn0AYyh6YxpREwwYS2J4LCIcZSsWVE91FkJ%2BfFUeRzgtFHsRUAUnAFgOZ2IGcH0eWWscaCtUK2FjKAwmS1F4IAsfAAU3VU8gFEJ%2BF0wxRRIaFHsRXAVFJRQhZH1%2Bf215Rn0BeDNXGhpKBR8hS2UhIBkmZi8eZEwOTEZ9eGAqQiQgKXozfD5HIXcPE2FCf1EsGVUSdyFkPyxPG2gIfmocIAkmZRY%2BbhECbnFFZEokRSQ9KHsvcjxHIXYPT3FBcn0wfWIvWh9kPjBHHh4QDmocJ3shAR0SZHooanVvQggpeA1aKGlYfwssIW4QZX1LdW8eZXwTaBJgOBJMKw01DWondRkIAA0OZE8kTXIaSlcreyg9LHsjYj0zB3UPT3IAcFErH1IoUgN7FjhoHx4MDGQndQknEmpxbREka0JFdEkqeBIlLBxcaA8gRxYQZEdbQn0kXFMpZCJQBBZOLRwHS2EnAj0mZQo0emE7GQ%3D%3D

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.
