WPF中的DataTemplate

<Window x:Class="DateTemplate应用.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:DateTemplate应用"
        xmlns:collections="clr-namespace:System.Collections;assembly=mscorlib"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <!--DataTemplate-->
        <DataTemplate DataType="{x:Type local:Unit}">
            <Grid>
                <StackPanel Orientation="Horizontal">
                    <Grid>
                        <Rectangle Stroke="Yellow" Fill="Orange" Width="{Binding Price}"/>
                        <TextBox Text="{Binding Year}"/>
                    </Grid>
                    <TextBlock Text="{Binding Price}" Margin="5,0"/>
                </StackPanel>
            </Grid>
        </DataTemplate>
        <!--数据源-->
        <collections:ArrayList x:Key="ds">
            <local:Unit Year="2001" Price="100"/>
            <local:Unit Year="2002" Price="120"/>
            <local:Unit Year="2003" Price="140"/>
            <local:Unit Year="2004" Price="160"/>
            <local:Unit Year="2006" Price="180"/>
            <local:Unit Year="2008" Price="200"/>
        </collections:ArrayList>
    </Window.Resources>
    <StackPanel>
        <ListBox ItemsSource="{StaticResource ds}"/>
        <ComboBox ItemsSource="{StaticResource ds}"/>
    </StackPanel>
</Window>

以XML数据格式来显示

<Window x:Class="XMLDataTemplate.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:xmlDataTemplate="clr-namespace:XMLDataTemplate"
        Title="MainWindow" Height="350" Width="525" WindowStartupLocation="CenterScreen">
    <Window.Resources>
        <!--DataTemplate-->
        <DataTemplate x:Key="MyXmlDataTemplate">
            <Grid>
                <StackPanel Orientation="Horizontal">
                    <Grid>
                        <Rectangle Stroke="Yellow" Fill="Orange" Width="{Binding XPath=@Price}"/>
                        <TextBlock Text="{Binding XPath=@Year}"/>
                    </Grid>
                    <TextBlock Text="{Binding XPath=@Price}" Margin="5,0"/>
                </StackPanel>
            </Grid>
        </DataTemplate>
        <!--数据源-->
        <XmlDataProvider x:Key="Ds"  XPath="Units/Unit">
            <x:XData>
                <Units xmlns="">
                    <Unit Year="2001" Price="100"/>
                    <Unit Year="2002" Price="120"/>
                    <Unit Year="2001" Price="140"/>
                    <Unit Year="2001" Price="160"/>
                    <Unit Year="2001" Price="180"/>
                    <Unit Year="2001" Price="200"/>
                    <Unit Year="2001" Price="220"/>
                </Units>
            </x:XData>
        </XmlDataProvider>
    </Window.Resources>
    <StackPanel>
        <ListBox ItemsSource="{Binding Source={StaticResource Ds}}" ItemTemplate="{StaticResource MyXmlDataTemplate}"/>
        <ComboBox ItemsSource="{Binding Source={StaticResource Ds}}" ItemTemplate="{StaticResource MyXmlDataTemplate}"/>
    </StackPanel>
</Window>

 显示层级数据的模板是HierarchicaDataTemplate

<?xml version="1.0" encoding="utf-8" ?>
<Data xmlns="">
  <Grade Name="一年级">
    <Class Name="1班">
      <Group Name="A组"/>
      <Group Name="B组"/>
      <Group Name="C组"/>
      <Group Name="D组"/>
    </Class>
  </Grade>
  <Grade Name="二年级">
    <Class Name="1班">
      <Group Name="A组"/>
      <Group Name="B组"/>
      <Group Name="C组"/>
      <Group Name="D组"/>
    </Class>
  </Grade>
  <Grade Name="三年级">
    <Class Name="1班">
      <Group Name="A组"/>
      <Group Name="B组"/>
      <Group Name="C组"/>
      <Group Name="D组"/>
    </Class>
  </Grade>
</Data>

<Window x:Class="TreeView.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <!--数据源-->
        <XmlDataProvider x:Key="ds" Source="Data.xml" XPath="Data/Grade"/>
        <!--年级模板-->
        <HierarchicalDataTemplate DataType="Grade" ItemsSource="{Binding XPath=Class}">
            <TextBlock Text="{Binding XPath=@Name}"></TextBlock>
        </HierarchicalDataTemplate>
        <!--班级模板-->
        <HierarchicalDataTemplate DataType="Class" ItemsSource="{Binding XPath=Group}">
            <RadioButton Content="{Binding XPath=@Name}" GroupName="gn"></RadioButton>
        </HierarchicalDataTemplate>
        <!--小组模板-->
        <HierarchicalDataTemplate DataType="Group" ItemsSource="{Binding XPath=Student}">
            <CheckBox Content="{Binding XPath=@Name}"></CheckBox>
        </HierarchicalDataTemplate>
    </Window.Resources>
    <Grid>
        <TreeView ItemsSource="{Binding Source={StaticResource ds}}"></TreeView>
    </Grid>
</Window>
