Property Value
Boolean: true to automatically recalculate formulas; false otherwiseRemarks
When this property is set to true, the Spread component automatically recalculates each formula when the contents of cells referenced by the formula change. When this property is set to false, cells with formulas are not updated when data changes.
If you have set this property to false, you can use the Recalculate method to force a recalculation of the formulas that have changed or the RecalculateAll method to force a recalculation of all formulas.
Define formulas using the Cell.Formula property, Row.Formula property, or Column.Formula property.
For more information about formulas, refer to the Formula Reference.
