|Access Developer Reference|
expression A variable that represents a CheckBox object.
The DisplayWhen property applies only to the following form sections: detail, form header, and form footer. It also applies to all controls (except page breaks) on a form.
The DisplayWhen property uses the following settings.
|Always||0||(Default) The object appears in Form view and when printed.|
|Print Only||1||The object is hidden in Form view but appears when printed.|
|Screen Only||2||The object appears in Form view but not when printed.|
For controls, you can set the default for this property by using the default control style or the DefaultControl property in Visual Basic.
In many cases, certain controls are useful only in Form view. To prevent Microsoft Access from printing these controls, you can set their DisplayWhen property to Screen Only. For example, you might have a command button or instructions on a form that you don't want printed. Or you might have form header and form footer sections that you don't want displayed on screen but that you do want printed. In this case, you should set the DisplayWhen property to Print Only.
For reports, use the Format and Retreat events to specify an event procedure or macro that sets the Visible property of controls you don't want printed. You can also cancel the Format or Print event for a report section to prevent the section from being printed.
