How to: Clear a Filter
- 2 minutes to read
The examples below demonstrate how to clear or disable a filter to redisplay all the rows in the filtered range.
Clear a filter from a column
To remove a filter from a specific column, access this column by its index in the AutoFilterColumnCollection collection, and then call the AutoFilterColumn.Clear method.
// Enable filtering for the specified cell range. Range 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); // Remove the filter from the SALES column. worksheet.AutoFilter.Columns[2].Clear();Clear all filters
To clear all the filters specified in a worksheet, use the AutoFilterBase.Clear method of the SheetAutoFilter object.

// Enable filtering for the specified cell range. Range 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); // Clear the filter. worksheet.AutoFilter.Clear();Disable a filter
To disable the filtering functionality, use the AutoFilterBase.Disable method of the SheetAutoFilter object. In this case, all the specified filters are removed, and the drop-down arrows disappear from the column headers in the filtered range.
