Occurs, if the document's text has been altered and the spelling of the new text must be checked. This event occurs only, if the SpellChecker property has been set to null and if the IsSpellCheckingEnabled property has been set to true. If a spell checking component has been connected with the ServerTextControl, this event is handled internally. The event handler receives an argument of type SpellCheckTextEventArgs containing data related to this event.
