Hi Jose,
We regret for the inconvenience caused.
The behavior of drag and drop was changed in the version of 15.X, drag preview tooltip will be visible on mouse click and hold (or touch and hold) with a time delay. Once the preview tooltip is displayed, now the row can be dragged and dropped at desired row position. Make sure that mouse pointer should not move within the time delay.
Please refer following demo video,
We are planned to change the current behavior of drag and drop in mouse action as per customers’ request. Going to implement as the previous behavior in the mouse action which can drag without time delay and touch action have some delay to display tooltip as similar as current working behavior. These changes will be available in our upcoming volume2, 2017 main release and it is expected to be rolled out by the end of April 2017
Regards,
Jayakumar D
