MSword in a web browser or any other server control that has ruler in it

I am developing asp.net with c#web application. I want to have a control in ASP.net that has text formatting controls as well as a ruler to edit the text which i enter in text area开发者_Go百科. It would be great if i can open Msword in a web browser without Save buttons at the client side.The data must be saved into the database.

The control should be similar to the one which i get while writing this question.and also e.g gmail compose mail.

My main aim is to provide right and left indentation to the text that is being entered and i want to preview on A4 size paper.

Please guide me someone the way to proceed.I got Htmleditor ajax control but it doesnot have a ruler.

You may take a look at WMD (this is what you are using for typing this question). You could also take a look at the many other alternative editors and pick one that suits your needs.
