I am writing a data entry program where the last field is going to be a RichTextBox for the user to enter remarks, formatted for print.
Is there a free or opensource .NET WinForms Rich Text Editor with all the GUI already implemented? Most searches end up with web based editors like FCKEditor and friends (or competitors, depending on how you see it).
I am totally going to start a new open source RichTextEditor if there isn't any (I highly doubt).
Here's one for WPF. And another one. And yet another one. And here's one for WinForms. So just pick any.
