I have a datagrid with a itemRenderer in one column which
displays a checkbox.
Outside of the datagrid I have Yes/No radio button group.
When the user selects Yes, I want all the checkboxes in the
datagrid to be checked and unchecked when they select No.
However I can't find a way to reference the checkboxes - can
anyone PLEASE tell me if there is a way to do this???
