FormulaResult Property (NamedReference)

Gets the value which will be used as the source in any calculations involving the NamedReference
Syntax
'Declaration
 
Public ReadOnly Property FormulaResult As Infragistics.Win.CalcEngine.UltraCalcValue
public Infragistics.Win.CalcEngine.UltraCalcValue FormulaResult {get;}
Remarks

Value returns the current value that any calculations referencing the NamedReference will use. If the NamedReference is the target of a formula, then this will be the last calculated value.

Note that the value may be an UltraCalcValueError.

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.
