You should hook to TextChanged event of TextBox, that fires as soon as some text is entered in the text box.

In the handler you can put your functionality of adding more text boxes.

I don't see how that will help on a web page.... are you sure this will work?

Well you did not mention "web" in your question, but, apparantly if you are using ASP .NET controls you'd be setting the runat property to server (runat="server"). This ensures that any value change in the textbox will cause a postback and will also hit your TextChanged event where you can add the behavior you require.

MVC is just a design pattern, it only changes the abstraction level, but the essence should be the same.
