I faced a problem when I don't allow user to assign the right of particular item (e.g. write field is empty that meant not available in member registration for example).

Create two containers, both with centered checkbox, one with enabled checkbox, another with disabled checkbox (or with no checkbox at all). Use Column.DynamicCurrentControl property to select what container will be shown depending on some field value.
