This example demonstrates how to specify the custom filter criteria to display dates that are before, after or equal to the specified date, or between two dates.
Worksheet worksheet = workbook.Worksheets["Regional sales"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Enable filtering for the specified cell range.
CellRange range = worksheet["B2:E23"];
worksheet.AutoFilter.Apply(range);
// Filter values in the "Reported Date" column to display dates that are between June 1, 2014 and February 1, 2015.
worksheet.AutoFilter.Columns[3].ApplyCustomFilter(new DateTime(2014, 6, 1), FilterComparisonOperator.GreaterThanOrEqual, new DateTime(2015, 2, 1), FilterComparisonOperator.LessThanOrEqual, true);
Dim worksheet As Worksheet = workbook.Worksheets("Regional sales")
workbook.Worksheets.ActiveWorksheet = worksheet
' Enable filtering for the specified cell range.
Dim range As CellRange = worksheet("B2:E23")
worksheet.AutoFilter.Apply(range)
' Filter the data in the "Product" column by an array of values.
worksheet.AutoFilter.Columns(1).ApplyFilterCriteria(New CellValue() { "Mozzarella di Giovanni", "Gorgonzola Telino" })
