How do I dynamically add controls to C# forms and read values in codebehind?

Question

I wonder if someone can help

I have a ASP.NET form and by clicking a button on the page user should be able to add new dynamic controls to it. the button click should be add one dropdown and two textboxes like append to a DIV or to panel.

How can this be done, thanks in advance.
