WPF的ComboBox 有些时候不能满足用户需求，需要对数据内容和样式进行自定义，下面就简要介绍一下用数据模板（DataTemplate）的方式对ComboBox 内容进行定制：
原型设计如下：
步骤：
1、新建一个WPF应用程序WpfAppDemo（VS2012)，并新建一个images文件夹（上传图片素材）;
2、在主界面MainWindow.xaml文件中添加一个Label、ComboBox 和Button控件,如下图：
代码如下：
1 <Window x:Class="WpfAppDemo.MainWindow"
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 Title="MainWindow" Height="350" Width="525">
5 <Grid>
6 <ComboBox x:Name="myColorComBox" HorizontalAlignment="Left" Margin="110,79,0,0" VerticalAlignment="Top" Width="309" Height="48" >
7 <!--ItemTemplate-->
8 <ComboBox.ItemTemplate>
9 <!--DataTemplate开始-->
10 <DataTemplate>
11 <Grid>
12 <Grid.ColumnDefinitions>
13 <ColumnDefinition Width="36"/>
14 <ColumnDefinition Width="100*"/>
15 </Grid.ColumnDefinitions>
16 <Grid.RowDefinitions>
17 <RowDefinition Height="50*"/>
18 <RowDefinition Height="50*"/>
19 </Grid.RowDefinitions>
20 <!--绑定数据对象Image属性-->
21 <Image Source="{Binding Image}" Width="32" Height="32" Margin="3,3,3,3" Grid.Row="0" Grid.Column="0" Grid.RowSpan="2" />
22 <!--绑定数据对象Name属性-->
23 <TextBlock Text="{Binding Name}" FontSize="12" Grid.Row="0" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center"/>
24 <!--绑定数据对象Desc属性-->
25 <TextBlock Text="{Binding Desc}" FontSize="10" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center"/>
26 </Grid>
27 </DataTemplate>
28 <!--DataTemplate结束-->
29 </ComboBox.ItemTemplate>
30 </ComboBox>
31 <Label Content="员工: " HorizontalAlignment="Left" Margin="66,92,0,0" VerticalAlignment="Top"/>
32 <Button Content="显示" HorizontalAlignment="Left" Margin="110,166,0,0" VerticalAlignment="Top" Width="75" Height="22" Click="Button_Click"/>
33
34 </Grid>
35
36 </Window>
3、在主界面MainWindow.xaml.cs文件中进行逻辑处理，代码如下：
1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Text;
5 using System.Threading.Tasks;
6 using System.Windows;
7 using System.Windows.Controls;
8 using System.Windows.Data;
9 using System.Windows.Documents;
10 using System.Windows.Input;
11 using System.Windows.Media;
12 using System.Windows.Media.Imaging;
13 using System.Windows.Navigation;
14 using System.Windows.Shapes;
15
16
17 namespace WpfAppDemo
18 {
19 /// <summary>
20 /// MainWindow.xaml 的交互逻辑
21 /// </summary>
22 public partial class MainWindow : Window
23 {
24 public MainWindow()
25 {
26 InitializeComponent();
27 //初始化数据，并绑定
28 LodData();
29 }
30
31
32 private void LodData()
33 {
34 IList<empoyee> customList = new List<empoyee>();
35 //项目文件中新建一个images文件夹，并上传了001.png，002.png,003.png
36 customList.Add(new empoyee() { ID ="001", Name = "Jack" ,Image="images/001.png",Desc="this is good gay!"});
37 customList.Add(new empoyee() { ID = "002", Name = "Smith", Image = "images/002.png", Desc = "this is great gay!" });
38 customList.Add(new empoyee() { ID = "003", Name = "Json", Image = "images/003.png", Desc = "this is the bset gay!" });
39
40
41 this.myColorComBox.ItemsSource = customList;//数据源绑定
42 this.myColorComBox.SelectedValue = customList[1];//默认选择项
43
44 }
45
46
47 private void Button_Click(object sender, RoutedEventArgs e)
48 {
49 //显示选择的员工ID信息
50 MessageBox.Show((this.myColorComBox.SelectedItem as empoyee).ID);
51 }
52
53
54
55
56
57 }
58 //定义员工类
59 public class empoyee
60 {
61 public string ID { get; set; }
62 public string Name { get; set; }
63 public string Image { get; set; }
64 public string Desc { get; set; }
65
66 }
67 }
4、编译运行，如果运气不错的话，应该能看到如下的界面：
