ColorScale2ConditionalFormatting Interface

Represents a two-color scale conditional formatting rule.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v19.1.Core.dll

Declaration

public interface ColorScale2ConditionalFormatting : ConditionalFormatting
Public Interface ColorScale2ConditionalFormatting
    Inherits ConditionalFormatting
public interface ColorScale2ConditionalFormatting : ConditionalFormatting
Public Interface ColorScale2ConditionalFormatting
    Inherits ConditionalFormatting

Remarks

The conditional formatting rule, which is specified by the ColorScale2ConditionalFormatting object, differentiates low and high values using a gradation of two colors. The Worksheet.ConditionalFormattings property returns the ConditionalFormattingCollection collection that stores all conditional formatting rules specified on a worksheet. Use the methods of the ConditionalFormattingCollection object to apply (the ConditionalFormattingCollection.AddColorScale2ConditionalFormatting method) or remove (the ConditionalFormattingCollection.Remove method) the conditional format.

Examples

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

  1. First of all, specify the minimum and maximum thresholds of a range using the ConditionalFormattingCollection.CreateValue method that creates an instance of the ConditionalFormattingValue object. This object provides access to threshold values and their types. The type of the threshold value is determined 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 ColorScale2ConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the ConditionalFormattingCollection.AddColorScale2ConditionalFormatting 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 maximum threshold specified by the ConditionalFormattingValue object.
    • A color corresponding to the maximum value in a range of cells.

To remove the ColorScale2ConditionalFormatting object, use the ConditionalFormattingCollection.Remove, ConditionalFormattingCollection.RemoveAt or ConditionalFormattingCollection.Clear methods.

Dim conditionalFormattings As ConditionalFormattingCollection = worksheet.ConditionalFormattings
    ' Set the minimum threshold to the lowest value in the range of cells.
    Dim minPoint As ConditionalFormattingValue = conditionalFormattings.CreateValue(ConditionalFormattingValueType.MinMax)
    ' Set the maximum threshold to the highest value in the range of cells.
    Dim maxPoint As ConditionalFormattingValue = conditionalFormattings.CreateValue(ConditionalFormattingValueType.MinMax)
' Create the two-color scale rule to differentiate low and high values in cells C2 through D15. Blue represents the lower values and yellow represents the higher values. 
Dim cfRule As ColorScale2ConditionalFormatting = conditionalFormattings.AddColorScale2ConditionalFormatting(worksheet.Range("$C$2:$D$15"), minPoint, Color.FromArgb(255, &H9D, &HE9, &HFA), maxPoint, Color.FromArgb(255, &HFF, &HF6, &HA9))
