list view
List objects (combo boxes, list boxes and option
buttons) display the contents of lists. As each object is placed in a report it
is named, by default, Listview[n], where n is a sequential number. Various
properties of list objects can be returned with formulas (for example,
=ListView[n].ElementCount
returns the number of elements
in the list). You can change the default name and use it in the formulas.
