Sorry Dmitry. I didn't realize this was an ASP.NET textbox. I was thinking WinForms. I didn't look at the category the question was posted in. To get this functionality, you will need to use javascript. Unfortunately, I don't know of any examples to point you to. There may also be third-party controls that provide this formating.
