// Create a new workbook and some local variables.
SpreadsheetGear.IWorkbook workbook = SpreadsheetGear.Factory.GetWorkbook();
SpreadsheetGear.IWorksheet worksheet = workbook.ActiveWorksheet;

// Add a title to a cell.
cells["A1"].Formula = "Unique Values";

// Get a reference to a range of cells.
SpreadsheetGear.IRange range = cells["A2:A11"];

// Load random data and format as $ using multiple cell range.

range.NumberFormat = "$#,##0_);($#,##0)";

// Set some duplicate values.
range[2, 0].Value = 100;
range[5, 0].Value = 100;

// Get a reference to the range's conditional formats collection.
SpreadsheetGear.IFormatConditions conditions = range.FormatConditions;
            
// Add unique values conditional format.
SpreadsheetGear.IFormatCondition condition = conditions.AddUniqueValues();

// Get a reference to the unique values condition.
