How to: Format Cells Using a Three-Color Scale

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E4929.

This example demonstrates how to apply a three-color scale conditional formatting rule.

  1. First of all, specify the minimum, midpoint and maximum thresholds of a range to which the rule will be applied. Threshold values are determined by the ConditionalFormattingValue object that can be accessed via the ConditionalFormattingCollection.CreateValue method. The type of the threshold value is specified by one of the ConditionalFormattingValueType enumeration values and can be a number, percent, formula, or percentile. Call the ConditionalFormattingCollection.CreateValue method with the ConditionalFormattingValueType.MinMax parameter to set the minimum and maximum thresholds to the lowest and highest values in a range of cells, respectively.

  2. To apply a conditional formatting rule represented by the ColorScale3ConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the ConditionalFormattingCollection.AddColorScale3ConditionalFormatting method with the following parameters:

    • A Range object that defines a range of cells to which the rule is applied.
    • A minimum threshold specified by the ConditionalFormattingValue object.
    • A color corresponding to the minimum value in a range of cells.
    • A midpoint threshold specified by the ConditionalFormattingValue object.
    • A color corresponding to the middle value in a range of cells.
    • A maximum threshold specified by the ConditionalFormattingValue object.
    • A color corresponding to the maximum value in a range of cells.

To remove the ColorScale3ConditionalFormatting object, use the ConditionalFormattingCollection.Remove, ConditionalFormattingCollection.RemoveAt or ConditionalFormattingCollection.Clear methods.

The image below shows the result. Cost distribution is shown using a gradation of three colors. Red represents the lower values, yellow represents the medium values and sky blue represents the higher values.
