Web.config registration missing! in Editor

[Gaurav]

Hi,

I am working with RadEditor. I have purchased premium controls pack.
Editor works fine but when we open a image manager it throw an error i.e.

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

My webconfig file code is :

<system.web>
 <httpHandlers>
      <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" />
      <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" />
      <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI" validate="false" />
    </httpHandlers>
    <httpModules>
      <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />
    </httpModules>
  </system.web>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <handlers>
      <add name="Telerik.Web.UI.DialogHandler.aspx" path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI" />
      <add name="Telerik_Web_UI_SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" />
    </handlers>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" preCondition="managedHandler" />
    </modules>
  </system.webServer>
</configuration>

and i am using routing without MVC architecture with asp.net 4.0 framework. and in global.asax file code is here

 routes.Ignore("{resource}.axd/{*pathInfo}");
routes.Ignore("Telerik.Web.UI.DialogHandler.aspx");

ignore for telerik controls.

these all code works fine in visual studio and run site from visual studio.

but it throws error while we run this site in IIS 7.0 or IIS 7.5.

and it shows a alert message and image manager page displays :

HTTP Error 500.21 - Internal Server Error

Handler "Telerik.Web.UI.DialogHandler.aspx" has a bad module "ManagedPipelineHandler" in its module list

message

How to resolve this error?????

Hi Gaurav,

If this line
routes.Ignore("{resource}.axd/{*pathInfo}")
skips (ignores) the *.axd handlers from the URL routing, you can open the web.config file and replace all instances of Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd

Web.config:
...
<httpHandlers>
       <add path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
...
</httpHandlers>
...
<handlers>
    <add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" />
...
</handlers>
...

After that set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd".

I'm having this same exact problem in IIS 7.5.  The screenshots are identical to what the original poster provided, except that I'm using .Net 2.0 instead of .Net 4.0, so i don't have those settings that the original poster had in his global.asax.  I'm not sure what i'm supposed to change in my web.config because the same site/code is working fine in IIS6.

Thanks!
