I'm trying to clear autofilters, but can't figure out how to do it. Is there any example code somewhere? IWorksheet.AutoFilters.FilterRange seems to be close, but how to set it to an empty range? I can't set it to null.

Hi Wout,

Thank you for your continued interest in Syncfusion products.

Currently it is not possible to clear filters. But you can workaround this by changing the current FilterRange. You can check the code snippet below.

sheet.AutoFilters.FilterRange = sheet[30,20];

Please try this and let me know if you have any questions.

I tried this workaround, which works ok luckily:

CType(newWorkSheet.AutoFilters, Syncfusion.XlsIO.Implementation.Collections.AutoFiltersCollection).Clear()

If the AutoFilters (IAutoFilters) interface could expose the Clear() method, then the ugly cast wouldn't be needed.

Best regards,

Hi Wout,

Thank you for the details.

I have logged a feature request on this regard and will get back to you once it is implemented.

I know this is an old question but is the suggested answer still the best solution:
((Syncfusion.XlsIO.Implementation.Collections.AutoFiltersCollection) worksheet.AutoFilters).Clear();

I need to remove the filters before saving my workbook under a different name (SaveAs) because the rows that are filtered out don't make it to the new workbook.

Hi Paul, 
You can unhide the filtered out rows after clearing the autofilters using ShowRange of IWorksheet . Please refer to below code to achieve the same. 
Code Example: 
                  (worksheet.AutoFilters as AutoFiltersCollection).Clear(); 
                  worksheet.ShowRange(worksheet.UsedRange, true); 
Please refer to below documentation to know more on show or hide specific range. 
Kindly try this and let us know if this meets your requirement.
