What to embed for a Richview Textbox with some formatting?

I have a webpage which has a textbox section in it. I want it to be similar like this image:

But not that much complicated regarding code fi开发者_JAVA技巧les goes. Want the user to edit some characters put some Bold/Underline/Italic fonts into it. Some smileys that all.

Any help?
