How to: Reapply a Filter

The example below demonstrates how to use the AutoFilterBase.ReApply method of the SheetAutoFilter object to reapply a filter after the data in the filtered range has been changed.

// Enable filtering for the specified cell range.
CellRange range = worksheet["B2:E23"];
worksheet.AutoFilter.Apply(range);

// Filter values in the "Sales" column that are greater than 5000$.
worksheet.AutoFilter.Columns[2].ApplyCustomFilter(5000, FilterComparisonOperator.GreaterThan);

// Change the data and reapply the filter.
worksheet["D3"].Value = 5000;
worksheet.AutoFilter.ReApply();
