I have a web farm with 3 servers. I am using RadEditor with Ajax spellchecker enabled on it in a web page.
I sometimes get the below report from the production servers:

Access to the path 'C:\PayrollPortalWWW\PayrollIssueWeb\App_Data\RadSpell\en-US-Custom.txt' is denied. |

When I click the Add to dictionary option in Spellchecker for a misspelled word, sometimes the word is added to the dictionary and I can see the word in the text file but sometimes the control just doesn't do anything and Misspelled word menu stays open. What could be the problem?
Thank you...

The problem could be due to insufficient permissions for the en-US-Custom.txt file. Can you please check whether the ASPNET / NETWORK SERVICE account has read / write permission?
If it has then try the following two suggestions:
You can change the default dictionary location and move them out of your application folder. For example:
| <telerik:RadEditor ID="RadEditor1" runat="Server"> |
| <SpellCheckSettings DictionaryPath="/common/RadSpell/" /> |
| ... |
In this case, the /common/RadSpell/ folder can be mapped to a different directory outside of your main web application. As long as the path in DictionaryPath can be mapped to a physical location, the spell check will work.
Another approach is to implement your own custom dictionary provider. Here is what you need to do:
1) create a class that implements the ICustomDictionarySource interface. Here is an example:
| public class myType : Telerik.Web.UI.Dictionaries.ICustomDictionarySource |
| { |
| #region ICustomDictionarySource Members |
| string _dictionaryPath; |
| public string DictionaryPath |
| { |
| get |
| { |
| return _dictionaryPath; |
| } |
| set |
| { |
| _dictionaryPath = value; |
| } |
| } |
| string _language; |
| public string Language |
| { |
| get |
| { |
| return _language; |
| } |
| set |
| { |
| _language = value; |
| } |
| } |
| string _customAppendix; |
| public string CustomAppendix |
| { |
| get |
| { |
| return _customAppendix; |
| } |
| set |
| { |
| _customAppendix = value; |
| } |
| } |
| public string ReadWord() |
| { |
| //return a string containing a word from the custom dictionary |
| //return null when there are no more words in the custom dictionary |
| return null; |
| } |
| public void AddWord(string word) |
| { |
| //implement custom code to add the word in your custom dictionary |
| } |
| #endregion |
| } |
The ReadWord function is called from the spell code as many times as you return a string. When you return null, the spell assumes there are no more words in the custom dictionary.
The AddWord function is called if the user chooses to add a new word to the custom dictionary.
2) set the CustomDictionarySourceTypeName in the SpellCheckSettings to the full type name of your custom provider. For example CustomDictionarySourceTypeName="myType, App_Code"

Thank you for your reply.
I already set the Spell Check Settings using the below code.
txtComments.SpellCheckSettings.DictionaryPath = GlobalParams.DictionaryLocation
If I set DictionaryLocation as a network location "\\XXX\YYY\RadSpell" it doesn't work but if I set DictionaryLocation as "~\App_Data\RadSpell" or "C:\XXX\YYY\RadSpell" it works.
I am using impersonation with identity impersonate and I can Create/Read files from "\\XXX\YYY\Uploads" directory from the same application. So I don't think that's an access problem because the account I use for impersonation has all the read&write permissions for both of the directories and files under them ("\\XXX\YYY\RadSpell" and "\\XXX\YYY\Uploads").
I don't plan to use custom dictionary provider for now so I'll first try to solve the problem with DictionaryPath.
Thank you...
