Server error, "Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies"

Hi

I have problems using the spell checker in RadEditor in Sharepoint.

This is what I get when I try to run the spellchecker :
 

I have versions 2010.2.826.20 and 2010.2.826.35 of Telerik.Web.UI.dll in GAC.

 

I add the languages and the spell checking dropdown box in the tools.xml file as following:

 

<tools name="InsertToolbar" enabled="true" >

<tool name="AjaxSpellCheck"/>

</tools>

 

<languages>

    <language code="de-DE" title="Deutsch" />

    <language code="en-US" title="Englisch" />

    <language code="fr-FR" title="France" />

    <language code="sv-SE" title="Svenska" />

</languages>

 

 

I have the dictionary files in all of the following folders:

• \Inetpub\Wwwroot\wss\VirtualDirectories\80\App_Data\RadSpell

• \Program Files\Common Files\Microsoft Shared\Web Server Extensions\wpresources\RadEditorSharePoint\5.8.0.0__1f131a624888eeed\Resources\App_Data\RadSpell
• \Program Files\Common Files\Microsoft Shared\Web Server Extensions\wpresources\RadEditorSharePoint\5.8.1.0__1f131a624888eeed\Resources\App_Data\RadSpell

 

This is how my web.config httpHandlers section looks like:

 

    <httpHandlers>

      <remove verb="GET,HEAD,POST" path="*" />

      <add verb="GET,HEAD,POST" path="*" type="Microsoft.SharePoint.ApplicationRuntime.SPHttpHandler, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

      <add verb="OPTIONS,PROPFIND,PUT,LOCK,UNLOCK,MOVE,COPY,GETLIB,PROPPATCH,MKCOL,DELETE,(GETSOURCE),(HEADSOURCE),(POSTSOURCE)" path="*" type="Microsoft.SharePoint.ApplicationRuntime.SPHttpHandler, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

      <add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />

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

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

    </httpHandlers>

 

And finally, in the onload method of the user control I tried any combination of the following lines of code, as well as any possible option for the SpellCheckProvider enumeration.

            editor.SpellCheckSettings.AllowAddCustom = true;

            editor.SpellCheckSettings.SpellCheckProvider = SpellCheckProvider.MicrosoftWordProvider;

            editor.SpellCheckSettings.EditDistance = 2;

            editor.SpellCheckSettings.AjaxUrl = "Telerik.Web.UI.SpellCheckHandler.axd";

 

FYI I am using the rad editor inside a roddock which is in a web user control. The web user control in turn is loaded into a sharepoint webpart.
I appreciate your help.

Hi Ali,

I can see that you are using RadEditor for MOSS. So when it comes to MOSS we recommend using MOSSRadEditor, which is defined in the Telerik.SharePoint namespace of the RadEditorSharePoint assembly. Once you use this control you do not need the following entries in the web.config:

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

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

If you still decide to use RadEditor instead MOSSRadEditor make sure that you always use fully qualified names when you register the handlers. Also review the following online KB 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

Thanks. I replaced RadEditor with MOSS RadEditor and the problem is now solved.
