I implemented drag-and-drop between grids without any problems, but how do you drop into a grid when it is empty? The problem can be reproduced on your demo at http://docs.telerik.com/kendo-ui/controls/data-management/grid/how-to/drag-and-drop-rows-between-two-grids by dragging/dropping each of the rows in one grid to the other grid until all the rows have been moved to the other grid. If you then try to drag/drop a row back to the original (now empty) grid, it won't let you drop into the empty grid.
