Request for adding an API support for Autofilters.
GemBox.Spreadsheet supports Autofilters only through the preservation in XLSX files.
Which means that if applied some autofilters in our XLSX file we can load our file with a GemBox.Spreadhsheet, make any required modifications and save it back to an XLSX format. The output file will contain autofilters from the original input file, but they are not directly supported by GemBox.Spreadsheet API.
The following link is a demonstration sample of preserving Autofilters when reading from XLSX file and writing to XLSX file:
More informations about GemBox.Spreadsheet's preservation can be found on the following link:
