Example
This example demonstrates how to create the rule that uses a formula as a criterion to apply a conditional format.
To create a new conditional formatting rule represented by the FormulaExpressionConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the
ConditionalFormattingCollection.AddFormulaExpressionConditionalFormatting
method. Pass the following parameters:- A Range object that defines a range of cells to which the rule is applied.
- A string value that determines a formula to evaluate.
- Specify formatting options to be applied to cells if the condition is true, using the ISupportsFormatting.Formatting property of the FormulaExpressionConditionalFormatting object.
To remove the FormulaExpressionConditionalFormatting object, use the ConditionalFormattingCollection.Remove, ConditionalFormattingCollection.RemoveAt or ConditionalFormattingCollection.Clear methods.

Dim cfRule As FormulaExpressionConditionalFormatting = worksheet.ConditionalFormattings.AddFormulaExpressionConditionalFormatting(worksheet.Range("$A$2:$G$15"), "=MOD(ROW(),2)=1")
' Specify formatting options to be applied to cells if the condition is true.
