Use regular expression to find value is in expected pattern. If you use this kind of textbox in many forms, I suggest making it as a custom control with all validation logic embedded. You can reuse it by dragging and dropping from toolbox.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia How to use google | Ask smart questions

You can hook JS keypress events of the texbox and check for the pattern. Regular expressions can be used here to check user has entered in the expected format. Here is a good RegEx tutorial, http://www.regular-expressions.info/[^]. Consider getting a good book on ASP.NET and Java Script.
