How to put formatting controls on top of textbox

Question

Hi Friends;


I want to create a textbox same like c# corner textbox with all the text formatting controls like above.

If you ask the question in c# corner or if u r giving reply to a question,then
u have to type the text in the text box control and on top of it we r seeing the text formatting controls (like B I U, to make text bold, italic , etc...)


how to keep those controls on top of the asp.net textbox, and how to stored the user modified data in textbox to database such that the display of text sould be in same format (bold text should display like bold and italic should display like italic... i think we have to save the html of the text in database if that is the case then how to convert text box text to html)
