public class DropTargetRenderer extends Canvas implements
IDropInListItemRenderer
{
private var _listData:DataGridListData;
private var textData:Text=new Text();
public function DropTargetRenderer()

super();
this.addEventListener(DragEvent.DRAG_ENTER,dragEnterHandler);
this.addEventListener(DragEvent.DRAG_EXIT,dragExitHandler);
this.addEventListener(DragEvent.DRAG_DROP,dragDropHandler);
}
public function get listData():BaseListData
{
return _listData;
}
public function set listData(value:BaseListData):void
{
_listData = DataGridListData(value);
}
override public function set data(value:Object):void
{
this.removeAllChildren()
super.data=value;
textData.text=String(data[_listData.dataField]);
this.addChild(textData);
}
public function dragEnterHandler(e:DragEvent):void{
var dropTarget:Text = e.currentTarget as Text;
if(e.dragSource.hasFormat('value')){
DragManager.acceptDragDrop(dropTarget);
}
}
public function
dragExitHandler(e:DragEvent):void{
var dropTarget:DataGridListData = e.currentTarget as
DataGridListData;
}
public function
dragDropHandler(e:DragEvent):void{
var value:String =
e.dragSource.dataForFormat('value') as String;
(e.currentTarget as Text).text +="\n"+ value

_listData = DataGridListData(value);
}
override public function set data(value:Object):void
{
// this.removeAllChildren()
super.data=value;
textData.text=String(data[_listData.dataField]);
this.addChild(textData);
}
public function dragEnterHandler(e:DragEvent):void{
var dropTarget:Text = e.currentTarget as Text;
if(e.dragSource.hasFormat('value')){
DragManager.acceptDragDrop(dropTarget);
}
}
public function
dragExitHandler(e:DragEvent):void{
var dropTarget:DataGridListData = e.currentTarget as
DataGridListData;
}
public function
dragDropHandler(e:DragEvent):void{
var value:String =
e.dragSource.dataForFormat('value') as String;
(e.currentTarget as Text).text +="\n"+ value
