I\'m using asp.net and I would like to edit a newsletter using CKEditor’s inline editing capabilities and then save the newsletter to the database and send via an email.
I believe this does exactly what you are looking for: ckeditor inline save/submit
You might need to change a few things to make it work for you. If you are writing valid HTML then I would suggest using something like Nokogiri to search and replace the contents of the page element id's instead of using regular expressions like this answer does.
