A filter by cell fill or font color.

Assembly : DevExpress.Printing.v25.2.Core.dll

NuGet Package : DevExpress.Printing.Core

Declaration

C#
VB.NET

csharp

public class XlColorFilter :
    IXlFilter,
    IXlFilterCriteria

Public Class XlColorFilter
    Implements IXlFilter,
               IXlFilterCriteria

Remarks

Create an instance of the XlColorFilter class and assign it to the XlFilterColumn.FilterCriteria or IXlTableColumn.FilterCriteria property to define the filter criteria for a worksheet or table column, respectively.

The XlColorFilter.Color property defines the color to filter by, and the XlColorFilter.FilterByCellColor property specifies whether the filter should use the cell color or font color as a filter criterion.

To filter a column by a pattern fill applied to its cells, you should additionally specify the XlColorFilter.PatternType and XlColorFilter.PatternColor properties of the pattern fill you wish to use in the filter.

Refer to the Filtering article to learn more about filtering in the Excel Export Library.
