CellRange.HasArrayFormula Property

Determines whether the current cell or cell range intersects a range filled with a legacy array formula.

Namespace: DevExpress.Spreadsheet

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

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

bool HasArrayFormula { get; }

VB.NET

ReadOnly Property HasArrayFormula As Boolean

Property Value

Type	Description
Boolean	true if the current range intersects an array formula range; otherwise, false.

Remarks

An Array formula is a formula that performs actions on two or more sets of values called array arguments. Each array argument must have the same number of rows and columns. The result of an array formula can be either a single value or multiple values. For detailed information, refer to the following article: Array Formulas.

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.
if (worksheet.Cells["C13"].HasArrayFormula) {
    string af = worksheet.Cells["C13"].ArrayFormula;
    worksheet.Cells["C13"].GetArrayFormulaRange().ArrayFormula = string.Empty;
    worksheet.Range.FromLTRB(2,1,2,10).ArrayFormula = af;
}
