wpf-DataTemplate应用

在WPF中，决定数据外观的是DataTemplate，即DataTemplate是数据内容的表现形式，一条数据显示成什么样子，是简单的文本还是直观的图形，就是由DataTemplate决定的。
下面通过设计ListBox及ComboBox控件的DataTemplate，把单调的数据显示成直观的柱状图。

 <Window x:Class="WpfDataTemplate.MainWindow"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         Title="MainWindow" Height="" Width="">
     <Window.Resources>
         <DataTemplate x:Key="MyItem">
             <StackPanel Orientation="Horizontal">
                 <Grid>
                     <Rectangle Stroke="Yellow" Fill="Orange" Width="{Binding Price}"></Rectangle>
                     <TextBlock Text="{Binding Year}"></TextBlock>
                 </Grid>
                 <TextBlock Text="{Binding Price}"></TextBlock>
             </StackPanel>
         </DataTemplate>
     </Window.Resources>

     <StackPanel>
         <ListBox ItemTemplate="{StaticResource MyItem}" x:Name="listBox1"></ListBox>
         <ComboBox ItemTemplate="{StaticResource MyItem}" x:Name="comboBox1"></ComboBox>
     </StackPanel>
 </Window>

后台代码：

 namespace WpfDataTemplate
 {
     /// <summary>
     /// Interaction logic for MainWindow.xaml
     /// </summary>
     public partial class MainWindow : Window
     {
         public MainWindow()
         {
             InitializeComponent();

             List<Unit> units = new List<Unit>();
             Unit unit1 = new Unit() { Year = "", Price =  };
             Unit unit2 = new Unit() { Year = "", Price =  };
             Unit unit3 = new Unit() { Year = "", Price =  };
             Unit unit4 = new Unit() { Year = "", Price =  };
             Unit unit5 = new Unit() { Year = "", Price =  };
             units.Add(unit1);
             units.Add(unit2);
             units.Add(unit3);
             units.Add(unit4);
             units.Add(unit5);

             listBox1.ItemsSource = units;
             comboBox1.ItemsSource = units;
         }
     }

     public class Unit
     {
         public string Year { get; set; }
         public int Price { get; set; }
     }
 }
