First i need to display data and after that drag and drop should work
below will display data
public class sampleItemRenderer extends Canvas implements
IDropInListItemRenderer
{
private var _listData:DataGridListData;
private var textData:Text=new Text();
private var str : String ="";
private var arr : Array ;
private var canvas:Canvas=new Canvas();
private var canvas1:Canvas=new Canvas();
public function sampleItemRenderer()
{
super();
}
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]);
textData.height=50;
textData.width=160
arr = textData.text.split(",");
var box:VBox=new VBox();
for(var i:int=0;i<arr.length;i++)
{
var text:Text = new Text();
text.text = arr[i].toString();
box.addChild(text);
this.addChild(box);
}
}
}
when i place your data drag and drop not happening
public function DropTargetRenderer()
{
super();
this.addEventListener(DragEvent.DRAG_ENTER,dragEnterHandler);
this.addEventListener(DragEvent.DRAG_EXIT,dragExitHandler);
this.addEventListener(DragEvent.DRAG_DROP,dragDropHandler);
}
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 += value
;
}
