Range Samples Conditional Formats Alternating Row Colors

Demonstrates using an Expression-based Conditional Format to create alternating row colors on a data range.

// Open workbook with a data range that needs formatting
SpreadsheetGear.IWorkbook workbook = 
SpreadsheetGear.IWorksheet worksheet = workbook.ActiveWorksheet;

// Get range that Conditional Formatting will be applied to.
SpreadsheetGear.IRange dataRange = worksheet.Cells["A2:D15"];

// Apply a uniform Theme Color and TintAndShade to the entire data range.
dataRange.Interior.ThemeColor = SpreadsheetGear.Themes.ColorSchemeIndex.Accent6;
dataRange.Interior.TintAndShade = 0.6; // 60% lighter

// Create an Expression-based conditional format, using the MOD(...) and ROW() 
// functions to alternate true/false values for each row of the data range.
SpreadsheetGear.IFormatCondition cf = dataRange.FormatConditions.Add(
    SpreadsheetGear.FormatConditionOperator.None, "=MOD(ROW(),2)=0", null);

// For every other row, apply the same Theme Color but slightly lighter TintAndShade.
cf.Interior.ThemeColor = SpreadsheetGear.Themes.ColorSchemeIndex.Accent6;
cf.Interior.TintAndShade = 0.8;  // 80% lighter
