        {
            fpSpread1.Sheets[0].Cells[0, 0].Value = 3;
            fpSpread1.Sheets[0].Cells[1, 0].Value = 2;
            fpSpread1.Sheets[0].Cells[1, 1].Value = 10;
            fpSpread1.Sheets[0].Cells[0, 2].Value = 1;            
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //Blank and NonBlank CF
            FarPoint.Win.Spread.BlankConditionalFormattingRule blank = new FarPoint.Win.Spread.BlankConditionalFormattingRule(true);
            blank.IsBlank = true;
            blank.BackColor = Color.LimeGreen;
            fpSpread1.ActiveSheet.SetConditionalFormatting(0, 1, blank);
//or
//Blank and NonBlank CF
//FarPoint.Win.Spread.BlankConditionalFormattingRule blank = new FarPoint.Win.Spread.BlankConditionalFormattingRule(true);
//blank.IsBlank = false;
//blank.FontStyle = new FarPoint.Win.Spread.SpreadFontStyle(RegularBoldItalicFontStyle.Bold);
//blank.BackColor = Color.LimeGreen;
//fpSpread1.ActiveSheet.SetConditionalFormatting(0, 0, 3, 3, blank);
        }
