NamedReferences Property

A collection of NamedReferences

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property NamedReferences As NamedReferencesCollection

C#

public NamedReferencesCollection NamedReferences {get;}

Remarks

NamedReferences are useful for creating formulas or constants that are used in other calculations but which will not be displayed to the user.

Example

Demonstrates setting up references for 2 TextBoxes which wil represent the height and width of a rectangle. The area of the rectangle is then calculated in a NamedReference. When the calculations are completed, the area is displayed in a third textbox.
