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;
compare.Actions.Add(linen);
fpSpread1.Sheets[0].AddValidators(new FarPoint.Win.Spread.Model.CellRange(1, 1, 1, 1), compare);
fpSpread1.Sheets[0].Cells[0, 0].Value = 10;
