That's because the KeyPress event happens before the text is changed. If you think about it, that's the only way it could work: the key that he pressed might not be a text key, it could be TAB, ENTER, a cursor movement, a Function key, ... or you could be trying to prevent alphabetic keys from working in a numeric only textbox say.
The KeyPressEventArgs has the KeyChar property which tells you what key was pressed, and the Handled property to allow you to prevent the key from going any further - if it;s set to true, then it stops there and the "normal" key processing doesn't happen.
