Returns or sets a value that determines whether there will be visible lines marking the margins.
The default setting is False.
If the AllowUserChangeMargins property is set to allow the user to change the margins, the user can also change the margins by dragging these lines.
If the Margins button is visible (see MarginsButtonVisible property), the user can toggle on and off the visibility of the margins by pressing that button.
If the button is not visible, the user can still show the margin lines by selecting a menu option.
