Telerik RadEditor spellchecker is not working

Question

Trying to implement spellcheck and I got a message:

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.

I did it by adding but still have the same message is coming up... I need some help please!

Answer 1

Regarding the Spell Check Handler Server Error, AjaxUrl property is used to set the path to the handler and is used in scenarios where you may have a UrlRewriter module which overwrites the handlers url even if they are set in the web.config. A correct value of this property is like follows: RadEditor1.SpellCheckSettings.AjaxUrl = "Telerik.Web.UI.SpellCheckHandler.aspx";

Once you set the new AjaxUrl value, go to the web.config file and update the Telerik.Web.UI.SpellCheckHandler.axd instances to Telerik.Web.UI.SpellCheckHandler.aspx
