        </Grid>
    </Window>

    后台代码很简单。。

    using System;
    using System.Collections.Generic;
    using System.Data;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Data;
    using System.Windows.Documents;
    using System.Windows.Input;
    using System.Windows.Media;
    using System.Windows.Media.Imaging;
    using System.Windows.Shapes;
    using WpfDemo.Class;
    namespace WpfDemo
    {
        /// <summary>
        /// WinDataGrid.xaml 的交互逻辑
        /// </summary>
        public partial class WinDataGrid : Window
        {
            DataBind db = new DataBind();
            private SolidColorBrush heiglihtbrush = new SolidColorBrush(Colors.Orange);
            private SolidColorBrush normalbrush = new SolidColorBrush(Colors.White);
            public WinDataGrid()
            {
                InitializeComponent();
            }
    
            private void Window_Loaded_1(object sender, RoutedEventArgs e)
            {
                datagrid.ItemsSource = db.GetProduct().DefaultView;
    
                
            }
    private void datagrid_LoadingRow(object sender, DataGridRowEventArgs e)
            {
                int i=e.Row.GetIndex();
                DataTable dt = db.GetProduct();
                if (int.Parse(dt.Rows[i]["unitcost"].ToString()) > 10)
                {
                    e.Row.Background = heiglihtbrush;
                }
                else
                {
                    e.Row.Background = normalbrush;
                }
            }
        }
    
        
    }
    namespace WpfDemo
    {
        public enum OrderStatus
        {
            None,
            New,
            Processing,
            Shipped,
            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。
