Well, the drag & drop process interferes with the mouse selection, because 
they are launched during the same mouse event.

I added the ability to prevent mouse events to propagate with STOP EVENT. This 
solves the selection of rows while dragging outside of the controls. But 
there is other interferences yet.

The only clean solution at the moment should be settings GridView selection 
mode to Select.None, and implements a selection mechanism yourself, by 
managing mouse events, and drawing selected rows differently in the Data 
event.
