Specifying the Field Source for a Field Chooser

The Field Source dialog box specifies the source of the fields that are displayed in the Field Chooser, and overrides the setting of the Data Source property for the dialog. The source can be any other Field Chooser or Target List control. You can choose to display the fields that are in the selected control or the fields, from the current data source, that are not in the selected control. The data source is determined by the Data Source property of the dialog.
