废话不说，看代码:
package
{
import flash.display.Sprite;
import mx.controls.DataGrid;
public class RowColorDataGrid extends DataGrid
{
public function RowColorDataGrid()
{
super();
}
override protected function drawRowBackground(s:Sprite,rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void{
if(dataIndex<super.dataProvider.length){
super.drawRowBackground(s, rowIndex, y, height, 0x49FFAD, dataIndex);
}else{
super.drawRowBackground(s, rowIndex, y, height, color, dataIndex);
}
}
}
}
先自定义一个DataGrid类，该类继承自DataGrid类。然后在自己的代码中引用该类即可，如下：
<?xml version="1.0"?>
