Grid event "BeforeRowDrop" not firing

The event “BeforeRowDrop” is not firing when dragging and dropping between 2 grids. According to my testing in this snippet it will fire when dropping back onto the source grid, but not on another grid.

I apologize for the delay with the reply.
Please, note that the beforeRowDrop event occurs for the target grid, and not for the source grid.

At this point, it doesn’t seem to be working at all. If you’ll notice in the snippet I created, the beforeRowDrop event is defined for both grids just in case, but never fires.

Thank you for your report. The problem is confirmed. We’ll try to fix it in the future updates.

We have fixed your reported problem in the latest 7.1.1 update.
Now the beforeRowDrop event shouold trigger correctly.
Thank you once again for your report.
