ig.excel.ArrayFormula

Represents an array formula for a group of cells.

Remarks

Array formulas are similar to regular formula in that they have the same grammar. However, array formulas must be set on a single region of cells only. When the array formula is applied to a region of cells, each cell's Formula property will be the array formula. The Value of each cell cannot be changed unless ArrayFormula.clearCellRange is called on the array formula or another value is applied to a region of cells which completely contains the array formula's region.

Because the array formula stores the region of the cells to which it is applied in the ArrayFormula.cellRange property, the array formula can only be applied to one region of cells.

Array formulas are created through Microsoft Excel by selecting a region of cells, entering a formula for that range, and pressing Ctrl+Shift+Enter. This causes the formula of each cell in the region to appear as follows: {=Formula}.

See the Microsoft Excel documentation for more information on array formulas.

    Applies the formula to all specified regions of cells.

    • regions
    • Type:ig.excel.WorksheetRegion[]
    • The regions of cells to apply the formula to.

    Exceptions

    Exception Description
    ig.ArgumentNullException regions is null.
    ig.ArgumentException regions has a length of 0.

    Remarks

    This method, or one of the other ApplyTo overrides must be used to set the value of a cell to a formula.

    After this method returns, the WorksheetCell.formula of all cells in all specified regions will return the formula.

  • clearCellRange

    .clearCellRange( );

    Removes this array formula as the formula for the cells to which it was applied.

    Remarks

    After this method returns, the ArrayFormula.cellRange will be null.

    .equalsStatic( formulaA:ig.excel.Formula, formulaB:ig.excel.Formula, cellReferenceMode:ig.excel.CellReferenceMode );
    Return Type:
    boolean
    Return Type Description:
    True if the formulas are both null or both equivalent; False otherwise.

    Determines whether two Formula instances are equal using the specified cell reference mode.

    • formulaA
    • Type:ig.excel.Formula
    • The first Formula to compare.

    Remarks

    This essentially performs a case-insensitive string comparison, ignoring the white space in the formula.
