    currcell.MinimumValue = 1;
    currcell.MaximumValue = 10;
    fpSpread1.ActiveSheet.Cells[1,1].CellType = currcell;
    fpSpread1.ActiveSheet.Cells[1,1].Note = "Pick a number between 1 and 10!";
    
    VB

    Dim currcell As New FarPoint.Win.Spread.CellType.CurrencyCellType()
    currcell.MinimumValue = 1
    currcell.MaximumValue = 10
