A ValueSignControl value that indicates the value sign.
The default is ValueSignControl.NoControl.
The ValueSign property determines what value can be accepted. If the value is ValueSignControl.Positive, only numbers that are not smaller than zero are allowed. If the value is ValueSignControl.Negative, only numbers that are not bigger than zero are allowed. ValueSignControl.NoControl means all numbers are allowed.
This example allows the user to type positive values in the cell.
GrapeCity.Win.Spread.InputMan.CellType.GcNumberCellType ncell1 = new GrapeCity.Win.Spread.InputMan.CellType.GcNumberCellType();            
ncell1.ValueSign = GrapeCity.Win.Spread.InputMan.CellType.ValueSignControl.Positive;
fpSpread1.Sheets[0].Cells[1, 1].CellType = ncell1;
Dim ncell1 As New GrapeCity.Win.Spread.InputMan.CellType.GcNumberCellType()
ncell1.ValueSign = GrapeCity.Win.Spread.InputMan.CellType.ValueSignControl.Positive
fpSpread1.Sheets(0).Cells(1, 1).CellType = ncell1
