Represents a conditional formatting rule that formats cells which are between or not between two values.
The conditional formatting rule specified by the RangeConditionalFormatting object highlights cells whose values are between or not between two specified values. 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.AddRangeConditionalFormatting method) or remove (the ConditionalFormattingCollection.Remove method) the conditional format.
This example demonstrates how to apply the conditional formatting rule, highlighting cells that are between or not between two values.
To create a new conditional formatting rule represented by the RangeConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the ConditionalFormattingCollection.AddRangeConditionalFormatting method. Pass the following parameters:
- A CellRange object that defines a range of cells to which the rule is applied.
- A condition specified by one of the ConditionalFormattingRangeCondition enumeration values.
- A string representing the low bound of the data subset inside or outside of which, formatted cells are located. Notice that the string can determine a formula to evaluate the lowest value.
- A string representing the high bound of the data subset inside or outside of which, formatted cells are located. Notice that the string can determine a formula to evaluate the highest value.
- Specify formatting options to be applied to cells if the condition is true using the ISupportsFormatting.Formatting property of the RangeConditionalFormatting object. Set the background and font colors.
// Create the rule to identify values below 7 and above 19 in cells F2 through F15. RangeConditionalFormatting cfRule = worksheet.ConditionalFormattings.AddRangeConditionalFormatting(worksheet.Range["$F$2:$F$15"], ConditionalFormattingRangeCondition.Outside, "7", "19"); // Specify formatting options to be applied to cells if the condition is true. // Set the background color to yellow. cfRule.Formatting.Fill.BackgroundColor = Color.FromArgb(255, 0xFA, 0xF7, 0xAA); // Set the font color to red. cfRule.Formatting.Font.Color = Color.Red;
