IXlSheet.EndFiltering() Method

Finishes filtering data in the cell range after calling the IXlSheet.BeginFiltering method.

Namespace: DevExpress.Export.Xl

Assembly: DevExpress.Printing.v24.1.Core.dll

NuGet Package: DevExpress.Printing.Core

Declaration

C#

void EndFiltering()

VB.NET

Sub

Remarks

To filter data in a cell range, do the following:

• Use the IXlSheet.AutoFilterColumns property to get access to the worksheet’s filter collection. Create an XlFilterColumn instance and add it to the collection to apply filtering to a specific column in a cell range. XlFilterColumn.ColumnId specifies the column’s zero-based index in the cell range you wish to filter, and the XlFilterColumn.FilterCriteria property defines the column’s filter criteria.
• Call the IXlSheet.BeginFiltering method to start filtering data using the specified filter criteria. Note that you can pass only the header row of the filter range to the method, since this range automatically extends when you generate new rows. If a row contains cells that do not meet the filter criteria, the row is hidden.
• Call the EndFiltering method to finish filtering after generating all the data.

For more examples on how to filter data in a worksheet using the Excel Export Library, refer to the Filtering topic.
