Hi Eliezer,

Could you please clarify your exact requirement for the spell checking functionality in the control? Do you wish to only highlight incorrect words or also have suggestions and a separate window as in the RadSpellChecker control?

As the RadSyntaxEditor control is intended for usage with code rather than text, it may not make sense to mark a certain word as incorrect in the context of a given language and implementing such a feature to work out of the box in all scenarios will not be straightforward. Would you please specify what language(s) you're planning to use this with and possibly give examples of other editors where support for such spell checking is present?

What I can recommend at this point is to implement this integration manually by defining a custom tagger to highlight any incorrect words and handle the DocumentContentChanged event to double-check on each keystroke.

I've prepared a small sample project to demonstrate what I have in mind. Please have a look and let me know if something similar would work for you.
