cnotify.InvalidCellStyle.BackColor = Color.Aqua;
FarPoint.Win.Spread.RequiredTypeValidator requiredt = new FarPoint.Win.Spread.RequiredTypeValidator();
requiredt.RequiredType = typeof(decimal);
requiredt.NullIsValid = true;
requiredt.Actions.Add(cnotify);

fpSpread1.Sheets[0].Cells[1, 1].Value = 5;

Visual Basic
