If you want to have checkboxed in all of your fields, you would have to retemplate the CellValuePresenter. You can find the default style in the DefaultStyles directory in the Infragistics folder. YOu can use that as a base to add checkboxed inside the ControlTemplate. Then, you can use DataTriggers/Triggers to see if the checkbox is/is not checked to determine what values should be saved in the database.
