Oh, I understand now why I could not reproduce this. I'm not using
Remo. I was on the issue, so thanks for the update.


You're right,

The

send "dgDragMove pMouseH, pMouseV" to sDataGridA[the dgControl of the target]

is indeed located in the "Track Drag & Drop" parent script of the
datagrid engine.


After more test, I'm not fully satisfy by the idea implements in the experiment:
using the dgTrackDragReorder property in the destination datagrid for
scrolling the dg during the dragMove, and replacing a
value in a column by using the DragReorderDrop event of the datagrid messages.

Copying a value in the right line is not accurate and the dragaction
is broken after a drop outside a droppable area.

Another way could consist to use the dgVScroll property for scrolling
the datagrid.

Will rework this experiment later.


Best regards,
