DataGird에서 Item 선택시 호출되는 이벤트 처리 입니다.
DataGird 속성은 반듯이 editable="true" 되어 있어야 해당 이벤트가 호출 됩니다.

DataGridEvent 객체

Property	Value
bubbles	false
cancelable	false
columnIndex	0부터 시작 / DataGrid의 열의 인덱스
currentTarget	이벤트를 처리하는 event listener를 정의하는 object
dataField	null
itemRenderer	편집중의 아이템에 대응하는 아이템 에디터 인스턴스
localX	NaN
reason	null
rowIndex	0부터 시작 / DataGrid의 행의 인덱스
target	이벤트를 dispatch한 object
Type	DataGridEvent.ITEM_FOCUS_IN

이벤트 등록

1. XML 속성으로 등록

<mx:DataGrid id = "grid1" editable="true" itemFocusIn="onItemFocusIn(event)">

2. 스크립트로 등록

grid1.addEventListener(DataGridEvent.ITEM_FOCUS_IN,onItemFocusIn);

이벤트 처리

   public function onItemFocusIn(e:DataGridEvent):void {
    var item:XMLList = new XMLList(grid1.dataProvider[e.rowIndex]);
    mx.controls.Alert.show("row = " + e.rowIndex + "\nitem value = \n" + item);
   }
