Property Value

A System.Object that represents the difference between the specified and compared values. The default is a null reference (Nothing in Visual Basic).
The validated value subtracts the compared value. You can compare the result with the DifferenceValue.
This example creates a compare cell validator.
//Type a value not equal to 20 to see the red line
FarPoint.Win.Spread.LineNotify linen = new FarPoint.Win.Spread.LineNotify();
linen.LineColor = Color.Red;
FarPoint.Win.Spread.CompareCellValidator compare = new FarPoint.Win.Spread.CompareCellValidator();
compare.ComparedOperator = FarPoint.Win.Spread.ValidateComparisonOperator.Equals;
compare.DifferenceValue = 10;
compare.NullIsValid = true;
compare.RequiredType = typeof(int);
compare.Row = 0;
compare.Column = 0;
fpSpread1.Sheets[0].AddValidators(new FarPoint.Win.Spread.Model.CellRange(1, 1, 1, 1), compare);
fpSpread1.Sheets[0].Cells[0, 0].Value = 10;
'Type a value Not equal to 20 to see the red line
Dim linen As New FarPoint.Win.Spread.LineNotify()
linen.LineColor = Color.Red
Dim compare As New FarPoint.Win.Spread.CompareCellValidator()
compare.ComparedOperator = FarPoint.Win.Spread.ValidateComparisonOperator.Equals
compare.DifferenceValue = 10
compare.NullIsValid = True
compare.RequiredType = GetType(Integer)
compare.Row = 0
compare.Column = 0
FpSpread1.Sheets(0).AddValidators(New FarPoint.Win.Spread.Model.CellRange(1, 1, 1, 1), compare)
FpSpread1.Sheets(0).Cells(0, 0).Value = 10
