    Using the Array Formula
    In This Topic

    You can use array formulas in Spread.

    An array formula is a formula that can perform multiple calculations on one or more items in an array. Array formulas can return multiple results or a single result.

    Use Ctrl + Shift + Enter to create an array formula after entering the formula at run time if the users are allowed to create formulas, or you can use the SetFormulaArray method.

    The following image displays an array formula in the Total column.

    Example of Array Formula

    Using Code

    The following example creates an array formula.

    C#
    Copy Code
    fpSpread1.ActiveSheet.ColumnHeader.Cells[0, 0].Text = "Units";
                    fpSpread1.ActiveSheet.ColumnHeader.Cells[0, 1].Text = "Price";
                    fpSpread1.ActiveSheet.ColumnHeader.Cells[0, 2].Text = "Total";
                    fpSpread1.ActiveSheet.Cells[0, 0].Value = 2;
                    fpSpread1.ActiveSheet.Cells[1, 0].Value = 5;
                    fpSpread1.ActiveSheet.Cells[2, 0].Value = 1;
                    fpSpread1.ActiveSheet.Cells[3, 0].Value = 9;
                    fpSpread1.ActiveSheet.Cells[0, 1].Value = 40;
                    fpSpread1.ActiveSheet.Cells[1, 1].Value = 100;
                    fpSpread1.ActiveSheet.Cells[2, 1].Value = 25;
                    fpSpread1.ActiveSheet.Cells[3, 1].Value = 80;
                    fpSpread1.AllowUserFormulas = true;
                    fpSpread1.ActiveSheet.SetFormulaArray(0, 2, 3, 2, "A1:A4*B1:B4");
    
    VB
    Copy Code
    fpSpread1.ActiveSheet.ColumnHeader.Cells(0, 0).Text = "Units"
                    fpSpread1.ActiveSheet.ColumnHeader.Cells(0, 1).Text = "Price"
                    fpSpread1.ActiveSheet.ColumnHeader.Cells(0, 2).Text = "Total"
                    fpSpread1.ActiveSheet.Cells(0, 0).Value = 2
                    fpSpread1.ActiveSheet.Cells(1, 0).Value = 5
                    fpSpread1.ActiveSheet.Cells(2, 0).Value = 1
                    fpSpread1.ActiveSheet.Cells(3, 0).Value = 9
                    fpSpread1.ActiveSheet.Cells(0, 1).Value = 40
                    fpSpread1.ActiveSheet.Cells(1, 1).Value = 100
                    fpSpread1.ActiveSheet.Cells(2, 1).Value = 25
                    fpSpread1.ActiveSheet.Cells(3, 1).Value = 80
                    fpSpread1.AllowUserFormulas = True
                    fpSpread1.ActiveSheet.SetFormulaArray(0, 2, 3, 2, "A1:A4*B1:B4")
