送分了！WPF数据绑定的一个菜鸟问题！

[dgw198906]

定义一个实体类
public class Counter
{public int Id { get; set; }
public string No { get; set; }
}；
然后定义一个泛型集合类IEnumerable<Counter> Get，用这个实体类为强类型，将一个数据库的数据读入到这个泛型集合中，返回值是Counter实体类。
那么我想请教的问题是怎么绑定这个泛型集合去datagrid？极度菜鸟的问题，各位大牛帮帮忙！送分了

DataContext属性即可
datagrid.DataContext = 方法返回的实体类集合;

[暖枫无敌]

错了，是ItemsSource 属性

MainPage.xaml内容：
<UserControl x:Class="SL1015.MainPage"

    <sdk:DataGrid Name="dataGrid1" AutoGenerateColumns="False" GridLinesVisibility="All">
        <sdk:DataGrid.Columns>
            <sdk:DataGridTextColumn Header="UserID" Binding="{Binding UserID}" IsReadOnly="True"></sdk:DataGridTextColumn>
            <sdk:DataGridTextColumn Header="UserName" Binding="{Binding UserName}" IsReadOnly="True"></sdk:DataGridTextColumn>
            <sdk:DataGridTemplateColumn Header="管理">
                <sdk:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="删除"></TextBlock>
                    </DataTemplate>
                </sdk:DataGridTemplateColumn.CellTemplate>
            </sdk:DataGridTemplateColumn>
        </sdk:DataGrid.Columns>
    </sdk:DataGrid>
</UserControl>

MainPage.xaml.cs的内容如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SL1015
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();

            dataGrid1.ItemsSource = GetDataList();
        }

        private List<Student> GetDataList()
        {
            List<Student> list = new List<Student>();
            list.Add(new Student(1, "张三"));
            list.Add(new Student(2, "李四"));
            list.Add(new Student(3, "王二"));
            list.Add(new Student(4, "麻子"));

            return list;
        }

    }
}

实体类Student.cs内容如下：

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SL1015
{
    public class Student
    {
        public Student(int id, string name)
        {
            this.UserID = id;
            this.UserName = name;
        }
        public int UserID { get; set; }
        public string UserName { get; set; }
    }
}

还是没明白我题目的用意。数据在实体类中，而实体类又在泛型集合中，等包裹了两层。我想问的是如何直接能绑定到datagrid中。
附数据从数据库中导入的方法：（注：用的enterprise library的数据连接）

public static IEnumerable<Counter> GetTicketHistoryByOrder(string tellerId)
{
var ticketHistoryMapper = MapBuilder<Counter>.BuildAllProperties();
var command = DbOperation.GetDbCommand(string.Format("select * from FES_QUEUE_TicketHistory where TellerID='{0}'", tellerId));
var results = DbOperation.ExecuteAstSqlStringAccessor<Counter>(command, ticketHistoryMapper);
}

[dgw198906]

public static IEnumerable<Counter> GetTicketHistoryByOrder(string tellerId)
  {
  var ticketHistoryMapper = MapBuilder<Counter>.BuildAllProperties();
  var command = DbOperation.GetDbCommand(string.Format("select * from FES_QUEUE_TicketHistory where TellerID='{0}'", tellerId));
  var results = DbOperation.ExecuteAstSqlStringAccessor<Counter>(command, ticketHistoryMapper);
  }

就是楼上的做法啊。 IEnumerable<Counter> 直接付给 DataGrid.ItemSource 有什么问题？

[暖枫无敌]

datagrid.ItemsSource = GetTicketHistoryByOrder(2).ToList();

[dgw198906]

两层数据的，绑进去空值了。

[暖枫无敌]

你返回的不就是实体类的集合嘛，什么两层数据，不懂

[dgw198906]

IEnumerable<Counter> result=DbOperation.ExecuteAstSqlStringAccessor<Counter>(command, ticketHistoryMapper);

数据写入代码
