Want to be able to drag over a grid row not before or after
I am using two grids where one is the dragable and the other the dropable. This works fine but I was wondering if there was a way to alter the way it looks. When I drag a row over my dropable row the dropable row is highlighted but there is also a line with arrows on either side implying the user can drop the row between, after or before the selected row which I don't allow. They can only drop on top of a row.
Any way to hide the arrows and line?
