Hello bitsbird ,

 Thank you for posting in our forum.

There’s no specific event handler on the UltraWebGrid for click on the white space under the rows.

You could however hook a click event handler for the grid’s container and check  if the target of the event is container grid.

If the target is the container grid then you’ve clicked in the white space under the rows, otherwise some other element inside the grid was clicked.

I’ve attached a sample for your reference. Please refer to it and let me know if you have any questions.

Best Regards,

Maya Kirova
