得到DataGrid列的值

<mx:DataGridColumn headerText="状态" dataField="D30120_ZH" width="80">
     <mx:itemRenderer>
      <mx:Component>

          override public function set data(value:Object):void {
           super.data = value;
           var dg:DataGrid = this.owner as DataGrid;
           if(dg && data){
            var dgc:DataGridColumn = dg.columns[listData.columnIndex] as DataGridColumn;
            var nowCellText:String=dgc.itemToLabel(value);
            if(nowCellText.indexOf("已缴纳费用")==-1){
             this.setStyle("color","black");

通过DataField: (仅仅是函数不同)

override public function set data(value:Object):void {
   super.data = value;
   var dg:DataGrid = this.owner as DataGrid;
   if(dg && data){
   　　var dgc:DataGridColumn =  dg.columns[listData.columnIndex] as DataGridColumn;
   　　//根据 dataField不同情况 配色
   　　if(data[dgc.dataField]== "0"){
      　　this.setStyle("color",0x7F7F7F);
   　　} else if(data[dgc.dataField]=="1"){
      　　this.setStyle("color","black");
   　　} else if (data[dgc.dataField]=="2") {
      　　this.setStyle("color",0xCD0000);
   　　} else if(data[dgc.dataField]=="3"){
     　　this.setStyle("color",0x008000);
   　　}   }
}
