  Hello,
  
  I am using asp.net ajax radeditor 2009.3.1314.35. I have tried the solution from "Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file." but no help. Actually on my localhost the solution works but on the server it always gives me this error and throws the dialog window to the login page.

  Web.config registration missing!
   The Telerik dialogs require a HttpHandler registration in the web.config file. Please, use the control's Smart Tag to add the handler automatically, or see the help for more information: Controls > RadEditor > Dialogs > Introduction
  ---------------------------
  OK   
  ---------------------------
  
  Any idea whats wrong ?

  Hi Syed,
  
  In form authentication scenario a non logged user is redirected to the login page. When a non user load some dialog then the code tried to load the login screen in the dialog, but the dialog expects other content and throws the reported error.
  
  The DialogHandler must be always accessible and to fix the problem you should add the following two <location> entries to the web.config:
  
  <location path="Telerik.Web.UI.DialogHandler.aspx">
      <system.web>
          <authorization>
              <allow roles="TestUser"/>
          </authorization>
      </system.web>
  </location>
  <location path="Telerik.Web.UI.SpellCheckHandler.axd">
      <system.web>
          <authorization>
              <allow roles="TestUser"/>
          </authorization>
      </system.web>
  </location>

  Hi,
  
  I have the same problem as Syed when using asp.net ajax radeditor. I have tried the 
  solution from "Error: Web.config registration missing! The Telerik 
  dialogs require a HttpHandler registration in the web.config file." but 
  no help. Actually on my localhost the solution works but on the server 
  it always gives me this error and throws the dialog window page when clicking on ImageManager or Hyperlink..

  Hello Vikas,
  
  You should delete the following handler in the web.config file
  
  <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
  
  and keep only this one:
  
  <add path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
  
  After that set the set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd".
  
  You can find more steps in this article: http://www.telerik.com/support/kb/aspnet-ajax/editor/error-web-config-registration-missing-the-telerik-dialogs-require-a-httphandler-registration-in-the-web-config-file.aspx
