I have a checkboxList on my page and its required that at least item is
checked. Is there a way to validate that at least one is checked when the
user clicks the 'submit' button?

there is no out-of-the-box solution build in ASP.NET to do that.
but you can implement your own validator control, implementing from the
BaseValidator class,
or try whether a existing solution do the work for you (first two results):
