Why don't you create two check boxes, one enabled, another disabled and switch them using DynamicCurrentControl?
You mentioned before that you wanted to avoid multiple controls, but sometimes I put more than five controls in one column and switch them depending on the values in the view. This way the sky is the limit, you can even put sometimes labels, image, textboxes etc into the column and create your own container controls as well.

This technique has helped me to create interfaces that are really intuitive and more interesting looking.
