SSpread.AllowDragDrop Property
Set whether to allow the user to move or copy cell blocks by dragging and dropping.
Specify $TRUE to allow it, or $FALSE to disallow it.
The initial value is $FALSE.
If allowed, the cell block can be moved by dragging the edge of the selected cell block. Hold down the Ctrl key while dragging to copy the cell block.
Dragging and dropping a cell block raises the DragDropBlock event.
The mouse cursor associated with drag and drop can be changed with the CursorIcon, CursorStyle, and CursorType properties.
