使用图形填充flex中的整行

Question

我有一个DataGrid，我需要根据条件更改特定行的背景颜色。我已达到这一点，但只有包含条件的单元格才会改变背景。我使用以下代码作为项呈示器。我需要以相同的方式填充对应于该单元格的整行

override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
        {
            super.updateDisplayList(unscaledWidth, unscaledHeight);
            var g:Graphics = graphics;
            g.clear();
            var grid1:AdvancedDataGrid = AdvancedDataGrid(AdvancedDataGridListData(listData).owner);

            //var rowtotal:int = new int(dp[0].length) ;
            if (grid1.isItemSelected(data) || grid1.isItemHighlighted(data))
                return;
            var dp:Array = Array((listData.owner as AdvancedDataGrid).dataProvider);
            var rowtotal:int = new int(dp[0].length) ;

            var i:int= new int(0);

            for (i=0; i < rowtotal; i++)
            {                   

            if (data[AdvancedDataGridListData(listData).dataField]== "NJ")
                 {
                 g.beginFill(0xCC0033);
                 g.drawRect(0, 0, unscaledWidth, unscaledHeight);

                 g.endFill();
                }
            }

      }
