后台代码很简单。。

    {
        DataBind db = new DataBind();
        private SolidColorBrush heiglihtbrush = new SolidColorBrush(Colors.Orange);

        public WinDataGrid()
        {

        private void Window_Loaded_1(object sender, RoutedEventArgs e)

        }

        {
            int i=e.Row.GetIndex();
            DataTable dt = db.GetProduct();
            if (int.Parse(dt.Rows[i]["unitcost"].ToString()) > )
            {
                e.Row.Background = heiglihtbrush;
            }
            else
            {
                e.Row.Background = normalbrush;
            }
        }
    }

}
namespace WpfDemo
{
    public enum OrderStatus
    {
        None,
        New,
        Processing,

        Received

}

做winfrom多了，不习惯wpf的绑定的方式。相信用的多了就好啦。理论上的东西，网上一搜一大片。就不复述了。这里只是一个简单的例子。
sql表如下。。没具体涵义。。就是为了实现例子拼凑的。
