Applies the "above or below average…" conditional formatting rule.

Namespace: DevExpress.Spreadsheet

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

Declaration

C#

AverageConditionalFormatting AddAverageConditionalFormatting(
    Range range,
    ConditionalFormattingAverageCondition condition
)

VB.NET

Function AddAverageConditionalFormatting(
    range As Range,
    condition As ConditionalFormattingAverageCondition
) As AverageConditionalFormatting

Parameters

Name	Type	Description
range	Range	A Range object that specifies a range of cells to which the conditional formatting rule is applied.
condition	ConditionalFormattingAverageCondition	One of the ConditionalFormattingAverageCondition enumeration values.

Returns

Type	Description
AverageConditionalFormatting	An AverageConditionalFormatting object that represents the specified conditional format.

Example

This example demonstrates how to apply an "above or below average" conditional formatting rule to a range of cells.

1. To create a new conditional formatting rule represented by the AverageConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the ConditionalFormattingCollection.AddAverageConditionalFormatting method. Pass the following parameters:

   • A Range object that defines a range of cells to which the rule is applied.
   • A condition specified by one of the ConditionalFormattingAverageCondition enumeration values.

   If you use the overloaded method with three parameters, pass the third parameter:

   • An integer value representing a number of standard deviations to be included above or below the mean in a range of cells.
2. Specify formatting options to be applied to cells if the condition is true using the ISupportsFormatting.Formatting property of the AverageConditionalFormatting object. Set the background color and specify the font attributes.

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