Bob,
1) In the datagrid source you need to have: the
dgTrackDragReorder[tTheIndex] set to false
If set to true, the datagrid tracks the move inside it. If set to
false you are allowed to move the data outside it.
Only this handler is required in the source datagrid:
on dragStart
local tTheIndex, tTheDragData, tTheDataControl
put the dgDataControl of the target into tTheDataControl
if (tTheDataControl is empty) then pass dragStart -- Prevent the
move if no data control exists
if (the dgHeader of the target is empty) then
put the dgIndex of the dgDataControl of the target into tTheIndex
set the dgDragImageIndex of me to tTheIndex
## Prepare the data to add in the datagrid 2
put the dgDataOfIndex[tTheIndex] of me into tTheDragData
combine tTheDragData using tab
set the dragData["private"] to tTheDragData
set the dgTrackDragReorder[tTheIndex] of me to false --
Important to move the data outside
end if
end dragStart
2) In the destination, you need two handlers:
on dragMove
set the dragaction to "copy"
end dragMove
The dragaction will allow the datagrid to get the data you drop.
on dragDrop
local tTheNewData, tTheColOrder
put "Col1" & cr & "Col2" into tTheColOrder
put the dragData["private"] into tTheNewData
send "AddLine tTheNewData, tTheColOrder" to me
end dragDrop
The dragDrop handler will receive the data dropped if the dragaction is allowed.
Best regards,
