JSON Error with Spell Control

[James Daresta]

I am using the spell in a page located in a sub folder on my site. It works fine on my local machine, but on our QA and production servers it fails with the following client side error.

I did a search and following previous posts I have not found a solution. Here is my control tag.

<telerik:RadSpell id="radspellEditCallReport_GeneralSpellCheckTop" runat="server" ControlsToCheck="txtEditCallReport_ExecutiveSummary,reEditCallReport_CallObjectives,reEditCallReport_CallDetails,reEditCallReport_ActionItems" ButtonType="None"  />

Here are my web.config entries

Ok using Fiddler I was able to determine an error was occurring on the server side. The error below was what I was getting. I fixed the issue by following the fix found in http://www.telerik.com/community/forums/aspnet-ajax/spell/500-error-on-dictionary-path.aspx. I used the step mentioned as follows:

I noticed that the dictionaries are located in the ~/App_Data/RadSpell folder which means that the DictionaryPath poperty should point that folder but not ~/RadSpell/en-us.tdf, e.g.

<asp:TextBox ID="TextBox9" runat="server"></asp:TextBox>

<telerik:RadSpell ID="RadSpell1" Runat="server" ControlToCheck="TextBox9"
  DictionaryPath="~/App_Data/RadSpell" SpellCheckProvider="TelerikProvider"
  ButtonType="PushButton" FragmentIgnoreOptions="All"
  SupportedLanguages="en-US,English" WordIgnoreOptions="None" />

The question I have is should I have to do it that way? I don't remember doing this previously in another project.

Exception message: No dictionary loaded. Set the DictionaryPath property from the spell checker settings or copy the dictionaries to ~/App_Data/RadSpell/

Hi James,

By default, the spellchecker looks for its dictionary file in the ~/App_Data/RadSpell directory and for this reason the DictionaryPath could be not set. But if in your scenario the DictionaryPath setting  (DictionaryPath="~/App_Data/RadSpell") is fixes the problem, then use it.

I was also facing same JSON issue on Spell check. But this issue was found only on pages which are under a sub-folder, pages under home directory were working fine.

I tried below code and its worked for me.


<telerik:RadEditor id="radE1" runat="server" DialogHandlerUrl = "~/Telerik.Web.UI.DialogHandler.axd">
            <SpellCheckSettings DictionaryPath="~/App_Data/RadSpell"   AjaxUrl="~/Telerik.Web.UI.SpellCheckHandler.axd" />
        </telerik:RadEditor>

For me removing "DictionaryPath" also working...
