SubForm.Visible (Access)
Returns or sets whether the object is visible.
To hide an object when printing, use the DisplayWhen property. You can use the Visible property to hide a control on a form or report by including the property in a macro or event procedure that runs when the Current event occurs. For example, you can show or hide a congratulatory message next to a salesperson's monthly sales total in a sales report, depending on the sales total.
