on ckeditor download website:
ASP.NET Control to easily integrate CKEditor on ASP.NET pages CKEditor.NET 3.6.4.
That means Can I use CKEditor` completely in asp.net without using javascript or jQuery?
If it is not possible,
What is the different between CKEditor 3.6.4 vs CKEditor 3.6.5?
Any tool is available like that
ckeditor is a client side editor, that works with javascript, is written on javascript.
The code behind is only used for save the content of the editor back to the database.
So the editor is only work with javascript.
