Property Value
String containing the formula for cells in this columnRemarks
Set this property to a mathematical expression made up of cell references, operators, and functions (either provided or custom functions you define). For a list of the operators and functions you can use in formulas, refer to the Spread for .NET Formula Reference.
The Spread component can use absolute or relative cell references. You define the cell reference style for the spreadsheet by using the ReferenceStyle property. The formula cannot contain both absolute and relative row or column references.
Returning the value of the Formula property provides a string containing the written expression of the formula, for example, SUM(A1:B1). However, if you have changed the cell reference style to a style that cannot represent the formula, the control provides the formula with question marks as placeholders for cell references that cannot be represented.
For example, if you have defined relative cell references used in a formula in cell B1 as RC[-1]+R[-1]C, the formula is interpreted as add the value in the cell to the left (A1) to the value in the cell above ("B0"). The control treats the value in the cell "B0" as an empty cell. If you change the cell reference style to the A1 style, the formula becomes A1+B?, because the A1 style cannot represent cell "B0". However, the control still evaluates the formula as it would using the R1C1 reference style.
