Range Samples Conditional Formats Color Scale

Create a Color Scale Conditional Format.

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

// Add a title to a cell.
cells["A1"].Formula = "Color Scale";

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

// Load data and format as $ using multiple cell range.
range.Formula = "=ROW() * 10 - 10";
range.NumberFormat = "$#,##0_);($#,##0)";

// Get a reference to the range's conditional formats collection.
SpreadsheetGear.IFormatConditions conditions = range.FormatConditions;
// Add color scale conditional format.
SpreadsheetGear.IFormatCondition condition = conditions.AddColorScale(2);

// Get a reference to the color scale.
SpreadsheetGear.IColorScale colorScale = condition.ColorScale;

// Set min and max scale values.
colorScale.ColorScaleCriteria[0].Type = SpreadsheetGear.ConditionValueTypes.Number;
colorScale.ColorScaleCriteria[0].Value = 0;
colorScale.ColorScaleCriteria[1].Type = SpreadsheetGear.ConditionValueTypes.Number;
colorScale.ColorScaleCriteria[1].Value = 100;
