This example demonstrates how to apply the conditional formatting rule, highlighting cells that are between or not between two values.

1. 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.
2. 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.

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

ConditionalFormatting.cs

// 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;

ConditionalFormatting.vb

' Create the rule to identify values below 7 and above 19 in cells F2 through F15.  
Dim cfRule As RangeConditionalFormatting = 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, &HFA, &HF7, &HAA)
' Set the font color to red.
cfRule.Formatting.Font.Color = Color.Red

The image below shows the result. Price values below $7 and above $19 are colored in yellow, and the font color is changed to red.
