Syntax
public interface IConditionalFormat : IParentApplication, IOptimizedUpdateRemarks
The formatting properties are applied if the conditional formatting rule evaluates to True.
Properties
AboveBelowAverage
Gets AboveBelowAverage conditional formatting rule. Read-only.
Declaration
IAboveBelowAverage AboveBelowAverage { get; }Property Value
| Type |
|---|
| IAboveBelowAverage |
Remarks
Valid only if FormatType is set to AboveBelowAverage.
Examples
AboveBelowAverage conditional formatting rule can be applied by setting AboveBelowAverage to FormatType property. To customize the AboveBelowAverage rule we have to change properties of IAboveBelowAverage interface. Here for example, we set values to IAboveBelowAverage interface properties.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

FirstFormula property is used to set value that is used for setting conditions. CellValue applies conditional formatting based on the condition from ExcelComparisonOperator enumeration. This requires atleast one value to apply conditional format. Here for example, we set "60" to FirstFormula property.

}TopBorderStyle
Gets or sets the top border line style.
Declaration
ExcelLineStyle TopBorderStyle { get; set; }Property Value
| Type |
|---|
| ExcelLineStyle |
Examples
To change the default line style of top border we set a line style from ExcelLineStyle enumeration to TopBorderStyle property. Here for example, we set Thick to TopBorderStyle property.

}TopBottom
Gets TopBottom conditional formatting rule. Read-only.
Declaration
ITopBottom TopBottom { get; }Property Value
| Type |
|---|
| ITopBottom |
Remarks
Valid only if FormatType is set to TopBottom.
Examples
TopBottom conditional formatting rule can be applied by setting TopBottom to FormatType property. To customize the TopBottom rule we have to change properties of ITopBottom interface. Here for example, we set values to ITopBottom interface properties.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);

IConditionalFormat format = formats.AddCondition();
//Set FormatType as TopBottom.
format.FormatType = ExcelCFType.TopBottom;
ITopBottom topBottom = format.TopBottom;
//Set values the ITopBottom interface properties.
topBottom.Type = ExcelCFTopBottomType.Bottom;
topBottom.Percent = false;
topBottom.Rank = 5;
//Set color.
format.BackColor = ExcelKnownColors.Red;
//Save and Dispose.
workbook.SaveAs("ConditionalFormats.xlsx");
workbook.Close();
}Underline
Gets or sets the underline type for the conditional format.
Declaration
ExcelUnderline Underline { get; set; }Property Value
| Type |
|---|
| ExcelUnderline |
Remarks
Similar to Underline, we can use IsStrikeThrough to strike out values in the cells within conditional formatting range.
Examples
Data in the cells can be given underline with the help of conditional formats. To give underline Underline property should be set to any of the value in the ExcelUnderline enumeration. Here for example, we set Double to Underline property.
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Create a worksheet.
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
//Load data to Apply Conditional Formatting.
worksheet["B1"].Text = "Conditional Formats";
worksheet["B2"].Number = 10;
worksheet["B3"].Number = 20;
worksheet["B4"].Number = 30;

//Set Condition.
format.FirstFormula = "60";
format.SecondFormula = "20";
