WPF模版主要分为俩大类：

ControlTemplate: 控件的外观，也就是控件是什么样子

DataTemplate: 是数据内容的表现，一条数据显示成什么样子

1. 数据模版常用的地方有以下几处：

ContentControl的ContentTemplate属性。
ItemsControl的ItemTemplate属性。
GridViewColumn的CellTemplate属性。

2. 示例

ItemsControl

ContentControl

3. DataTemplate除了可以作用在控件上，也可以作用再数据类型上

<Window x:Class="DeepXAML.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:DeepXAML"       
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
         xmlns:cl="clr-namespace:System.Collections;assembly=mscorlib"
        Title="MainWindow" Height="250" Width="450">
    <Window.Resources>
        <DataTemplate DataType="{x:Type local:Student}">            
            <StackPanel Orientation="Horizontal" >
            <Grid Margin="5">                
                <Rectangle Fill="YellowGreen"  Width="{Binding  Path=Score}"/>
                <TextBlock  Text="{Binding Path=Name}"></TextBlock>
            </Grid>
                <TextBlock Text="{Binding Path=Score}" Margin="5"></TextBlock>
            </StackPanel>
        </DataTemplate>
        <cl:ArrayList x:Key="allStudentsList">
            <local:Student Name="Jack" Gender="True" Score="80"></local:Student>
            <local:Student Name="Tom" Gender="False" Score="40"></local:Student>
            <local:Student Name="Jack" Gender="True" Score="75"></local:Student>
        </cl:ArrayList>
    </Window.Resources>
    <StackPanel x:Name="stackPanel">
        <ListBox ItemsSource="{StaticResource ResourceKey=allStudentsList}" FontSize="15"></ListBox>
        <TextBlock Margin="10">Below is combox</TextBlock>
        <ComboBox ItemsSource="{StaticResource ResourceKey=allStudentsList}" FontSize="15"></ComboBox>
    </StackPanel>
</Window>

4. DataTemplate作用在XML元素上

<Window x:Class="DeepXAML.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:DeepXAML"       
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
         xmlns:cl="clr-namespace:System.Collections;assembly=mscorlib"
        Title="MainWindow" Height="250" Width="450">
    <Window.Resources>
        <DataTemplate DataType="Student">            
            <StackPanel Orientation="Horizontal" >
            <Grid Margin="5">                
                <Rectangle Fill="YellowGreen"  Width="{Binding  XPath=@Score}"/>
                <TextBlock  Text="{Binding XPath=@Name}"></TextBlock>
            </Grid>
                <TextBlock Text="{Binding XPath=@Score}" Margin="5"></TextBlock>
            </StackPanel>
        </DataTemplate>
        <XmlDataProvider x:Key="xmlDp" XPath="Students/Student">
            <x:XData>
                <Students xmlns="">
                    <Student Name="Jack" Score="80"></Student>
                    <Student Name="Tom" Score="40"></Student>
                    <Student Name="David" Score="75"></Student>
                </Students>
            </x:XData>
        </XmlDataProvider>
    </Window.Resources>
    <StackPanel x:Name="stackPanel">
        <ListBox ItemsSource="{Binding Source={StaticResource xmlDp}}" FontSize="15"></ListBox>
        <TextBlock Margin="10">Below is combox</TextBlock>
        <ComboBox ItemsSource="{Binding Source={StaticResource xmlDp}}" FontSize="15"></ComboBox>
    </StackPanel>
</Window>
