Hi,
We handle something very similar to this, and although we don't deny a
drop based on the index, we use the index to persist the drop location
in the database...the same logic applies. We are using this on an ADG
and hence my example below:
You could grab the internal targetGrids dropData get the
dropData.index...check it and if its not the value you want, perform an
event.preventDefault and stopPropagation...
private function adg_DragEvent(event:DragEvent):void
{
var targetGrid:AdvancedDataGrid = event.currentTarget as
AdvancedDataGrid;
use namespace mx_internal;
var dropData:Object = targetGrid.mx_internal::_dropData;
adgIndex = dropData.index;
if (adgIndex > 4)
{
targetGrid.hideDropFeedback(event);
targetGrid.selectedItems = new Array();
event.preventDefault();
event.stopPropagation();
}
}
HTH!

The problem I'm facing is that even though my dragEnter event handler
doesn't call the DragManager.acceptDragDrop(UIComponent), it still
allows me to drop it.
