Currently its not allow to do Sorting while filter was activated.
its not connivance and it required to switch off the filter each time i want to sort.
@Alon Moshe -thanks for posting this. I've never understood this limitation in Smartsheet. I'm assuming the developers have a good reason for it. But the lack of flexibility makes Smartsheet's filtering and sorting functionality lag behind the competition like Google Sheets, Excel, and Quip, to name a few.

I understand this frustration, and have since started to use Reports for this reason because rows are automatically sorted regardless of when they are added to sheet (another feature that isn't available in Grid Sheet).
