Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

string ArrayFormula { get; set; }

VB.NET

Property ArrayFormula As String

Property Value

Type	Description
String	A string that is the array formula.

Remarks

An array formula is a special kind of formula used to perform calculations with arrays of cells. For detailed information, see the Array Formulas topic.

Example

This example creates a legacy array formula:

FormulaActions.cs

// Create an array formula that multiplies values contained in the cell range A2 through A11 
// by the corresponding cells in the range B2 through B11, 
// and displays the results in cells C2 through C11.
worksheet.Range.FromLTRB(2,1,2,10).ArrayFormula = "=A2:A11*B2:B11";

// Create an array formula that multiplies values contained in the cell range C2 through C11 by 2
// and displays the results in cells D2 through D11.
worksheet.Range["D2:D11"].ArrayFormula = "=C2:C11*2";

// Create an array formula that multiplies values contained in the cell range B2 through D11, 
// adds the results, and displays the total sum in cell D12.
worksheet.Cells["D12"].ArrayFormula = "=SUM(B2:B11*C2:C11*D2:D11)";

// Re-dimension an array formula range:
// delete the array formula and create a new range with the same formula.
