Hi Divyesh Chapaneri,
Thank you for your question. This property no longer exists, but by default multi-column sorting is enabled. In order to use it, please use the
Shift + mouse click on the header row to perform the second sorting. I have updated our help and the change will be soon visible.
Do not hesitate to write me back if you have more questions.
Best wishes,
Nick
