我没有尝试使用，AdvancedDataGrid但是当我尝试设置我的DataGrid. 我通过创建自定义DataGrid（mxml）然后使用以下方法来做到这一点：

override protected function drawRowBackground(s:Sprite, rowIndex:int,
                    y:Number, height:Number, color:uint, dataIndex:int):void
{
    if( this.rowColorFunction != null )
    {
        if( dataIndex < (this.dataProvider as ArrayCollection).length )
        {
            var item:Object = (this.dataProvider as ArrayCollection).getItemAt(dataIndex);
            color = this.rowColorFunction.call(this, item, dataIndex, color);
        }
    }

    super.drawRowBackground(s, rowIndex, y, height, color, dataIndex);
}


public function set rowColorFunction(f:Function):void
{
    this._rowColorFunction = f;
}

public function get rowColorFunction():Function
{
    return this._rowColorFunction;
}

例子：

myGrid.rowColorFunction = function(item:Object, dataIndex:int, color:uint):uint
{
    //conditions then return your color here
}
