Anyone help me with this?  I need to have a list/spread/grid of table
data (maintainable by the user) where one of the columns is linked to a
boolean data type, which I want to display as a checkbox.

????

How about placing a check box array on the same form at load, reading the
boolean and setting the check boxes when the data for the grid/spread is
read, meanwhile hiding that column so the info is not duplicated.

A change event on the check boxes can then change the boolean in question.
