The mechanism behind the postback model in WebForms is called HTTP POST. This is how user input is communicated back to the server.

You can do it manually. Attach a JavaScript handler manually to the checkbox "onclick" event and perform a POST request to some url. There, this request will hit some controller action where you do what you want. For example, update the model (check/uncheck the checkbox) and return the same view from which the POST originated. The view will now show the different state for the checkbox.

The WebForms mechanisms do pretty much the same, though these things are abstracted away from you. With ASP.NET MVC you'll need to learn how to do it on your own (which is always a good thing).
