Answer 1

Maybe you could extend the mentioned CheckedListBox, and handle a few Events so that only the first CheckBox is visible (maybe some kind of formatting event would be good for that).

And don't forget to use the onCheckedChangeEvent, so that you (de-)select all elements on change of the checkbox-value.
