Telerik.Web.UI.DialogHandler.aspx 404

[Robb Blacquiere]

Hi,

I'm trying to use the Image Manager and Hyperlink Manager with my editor.  It is working fine on my local development machine as well as my local QA server.  But, when I upload the project to my clients shared hosting environment I get a 404 on the 'Telerik.Web.UI.DialogHandler.aspx'.  The handler is set up correctly in the web.config as I used the smart tag to set it up and the hosting environment is not IIS 7.0 .

I've been trying to do some debugging in Firebug and found the 'Telerik.Web.UI.DialogHandler.aspx?checkHandler=true' returns a 200 status.

I haven't found a similar issue in the forums, so your assistance is very much appreciated.

Thanks.

Hi Robb,

Please, open the web.config file and rename the handler extension from .aspx to .axd , e.g.
Telerik.Web.UI.DialogHandler.axd

After that set the value of the RadEditor's DialogHandlerUrl property to Telerik.Web.UI.DialogHandler.axd

If your project is running in IIS7 then you should make sure that you have changed the aspx extension to axd in the system.web and system.webserver sections.

I'm having the same issue in my dev server -- I changed the handler extension from .aspx to .axd, but it sill doesn't work. Any ideas?

<system.web>
    ....


    <httpHandlers>
      ....
      <add path="Telerik.Web.UI.DialogHandler.axd" verb="*" type="Telerik.Web.UI.DialogHandler" validate="false" />
   </httpHandlers>

</system.web>

<system.webServer>
    ...
    <handlers>
      ....
      <add name="Telerik_Web_UI_DialogHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" />
    </handlers>

</system.webServer>



Thanks,

Ivan

Hi Ivan,

Please, try the suggestions provided in the following KB article:
Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file.

Rumen,

Thanks for replying. None of the suggestions in the KB apply to my case: the handler is already registered in web.config, there are no other handlers intercepting the request, and my dev server uses IIS 5.0. I do use a URL rewriter, but it is set to work with only one specific file (I did turn the URL rewriter off just to test, but I still had the same problem).

Anything else I could try?

Thanks,

Ivan

Hi Ivan,

It will be best if you can provide a live URL to the problematic page with RadEditor where we can test the dialogs and see what is causing the error.

Rumen,

Unfortunately, our development site is only accessed from within the intranet! As I mentioned before, though, the web.config seems to be configured correctly (see previous post), and the DialogHandlerUrl is set to "Telerik.Web.UI.DialogHandler.axd." Anything else I can try?

Thanks,

Ivan

Hi Ivan,

Can you please try to set the value of the DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd"
and "/Telerik.Web.UI.DialogHandler.axd" and see whether this helps?

Please, also open a support ticket and send your web.config file.

Kind regards,

Thanks Rumen,

Still the same. I opened a support ticket.

Rumen,

My issue has been solved. I opened a support ticket as you suggested, and Dobromir pointed me to http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/another-solution-to-dialogs-returning-404-errors.aspx . Even though we have IIS 5.0 on the dev server, we use URLScan to set the max length of querystring (which was set to 200). I changed it to 1000, and things are fine now.

Thanks,

Ivan
