the dragdestination wierdness

[Bob Sneidar]

Here's an update. Seems I was overcomplicating things by trying to read the API docs and not knowing what I was doing. This works:

on dragStart
   put the dgDataControl of the target into theDataControl
   
   ## Watch out for dragging on the header
   if theDataControl is empty then pass dragStart
   
   ## Get Data Grid index of control that was clicked on
   put the dgDataControl of the target into theTargetLongID
   put the dgIndex of the dgDataControl of the target into theIndex
   
   ## Tell Data Grid to set the dragImage to the row 
   ## that theIndex is associated with
   set the dgDragImageIndex of me to theIndex
   
   ## Set the dragData["private"] so that drag operation
   ## begins
   set the dragData["private"] to the short name of theDataControl
    
   set the dgTrackDragReorder[theIndex] of me to true
end dragStart
   
on DragDrop
   put dragData["private"] into theDropSource
   put the short name of the dgDataControl of the target into theDropTarget
   put theDropSource & return & theDropTarget 
end DragDrop  

This returns: 
SecFields 0001
SecFields 0002

As expected, or more specifically, the source of the drag and the destination of the drop. I didn't know "the dgDataControl of the target" changed when I executed a drag and drop. I thought it only referred to the source of the drag.
