I'm exploring how to implement a set of images that function similar to radio buttons. The idea is that when a user clicks on an image, a check mark would be displayed below it to indicate selection. I think I can achieve this using an onclick event and some CSS for the check mark display. However, I am unsure of the best approach to take in ASP.NET for this functionality and also need to figure out how to transmit the selected data to the server through a form submission.
