A filter by a list of cell values or date and time values.

Namespace: DevExpress.Export.Xl

Assembly: DevExpress.Printing.v19.2.Core.dll

Declaration

C#

public class XlValuesFilter :
    IXlFilter,
    IXlFilterCriteria

VB.NET

Public Class XlValuesFilter
    Implements IXlFilter,
               IXlFilterCriteria

Remarks

Create an instance of the XlValuesFilter 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 XlValuesFilter.Values property allows you to specify cell values that should be included in the filtering results.

Use the XlValuesFilter.DateGroups property to filter a column by date and time values.

You can include blank cells in a filter by setting the XlValuesFilter.FilterByBlank property to true.

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