asp.net - (ASP Web Forms) Dynamically add controls while keeping info after postback?

Question

Let's say I have a bunch of controls that I want to "repeat" on the page. The user can click "Add" to add another set of controls.

I still want the input to be kept (that the user has put in) after the postback that will be triggered when the user clicks "Add".?

What is the best way to do this? I would like to use a repeater but then you have to (as far as I know) store the information in ViewState and then re-populate all the controls with the old data.

I am using ASP Web Forms.
