For checking the text entered in a textbox, you might want to use the TextChanged event, which is triggered only after the textBox loses focus. You can hook it up either in javascript (client) or in code (server).
Another option is to have some validator to restrict the allowed characters. You might want to take a look at this article from MSDN: http://msdn.microsoft.com/en-us/library/ms998267.aspx (How To: Use Regular Expressions to Constrain Input in ASP.NET).
