ConditionalFormattingCollection.AddFormulaExpressionConditionalFormatting(CellRange, String) Method

Applies a conditional formatting rule that uses a formula to determine which cells to format.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v22.2.Core.dll


FormulaExpressionConditionalFormatting AddFormulaExpressionConditionalFormatting(
    CellRange range,
    string expression


Name Type Description
range CellRange

A cell range to which the conditional formatting rule is applied.

expression String

A formula in the invariant culture. Start the formula with an equal sign (=). The formula can include the Spreadsheet’s built-in functions. You can combine relative and absolute references to adjust the formula in each cell if necessary.


Type Description

The conditional formatting rule that this method creates.


This example demonstrates how to create the rule that uses a formula as a criterion to apply a conditional format.

  1. 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 CellRange object that defines a range of cells to which the rule is applied.
    • A string value that determines a formula to evaluate.
  2. Specify formatting options to be applied to cells if the condition is true, using the ISupportsFormatting.Formatting property of the FormulaExpressionConditionalFormatting object.


Transparency is not supported in conditional formatting.

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

View Example

// Create the rule to shade alternate rows without applying a new style.
FormulaExpressionConditionalFormatting cfRule = 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.
// Set the background color to light blue.
cfRule.Formatting.Fill.BackgroundColor = Color.FromArgb(255, 0xBC, 0xDA, 0xF7);
