I'm working on a card program that gives the user the ability to select different decks. I'm going to display the decks using pictureboxes. I would like it so that when a user clicks on a deck, there is some form of outline so they know which deck is currently selected. Then, based on that selection, when they click OK, it passes a variable back to the original form to indicate which deck was selected. Does anyone know an easy way to do this or can it only be done using a radio button?
