I writing this program that tests the user on the given questions and answers. Now, I'm giving them the option to have multiple choice, fill in the blank, True and Fasle, etc. My question is this...

So, just imagine a static (with the question) and, for example, four radio buttons for multiple choice. But! The next question is a fill-in-the-blank! Which is a static and a text box. How would I go about changing/hiding the four radio buttons from the previous type of question? What I mean is, there are going to be a couple of controls, but then when the type of question changes, there are going to have to be different controls for the different types of questions. How would I do this? Hide all of the controls and then when I need them hide the ones that are on and make the ones needed unhidden? How would I do this?
