ListView中使用DataTemplete

xaml:

<Window.Resources>
<c:ArrayList x:Key="stuList">
<local:Student Name="张三" Age="20" Skill="三年级" />
<local:Student Name="李四" Age="21" Skill="二年级" />
<local:Student Name="王五" Age="23" Skill="三年级" />
<local:Student Name="王二" Age="26" Skill="五年级" />
<local:Student Name="Tom" Age="15" Skill="一年级" />
</c:ArrayList>
<DataTemplate x:Key="NameDT">
<TextBox x:Name="tName" Text="{Binding Name}" GotFocus="tName_GotFocus"></TextBox>
</DataTemplate>
<DataTemplate x:Key="AgeDT">
<TextBlock x:Name="tAge" Text="{Binding Age}"></TextBlock>
</DataTemplate>
<DataTemplate x:Key="SkillDT">
<TextBlock x:Name="tSkill" Text="{Binding Skill}">
</TextBlock>
</DataTemplate>
</Window.Resources>
<Grid>
<ListView x:Name="listV" ItemsSource="{StaticResource stuList}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" CellTemplate="{StaticResource NameDT}" />
<GridViewColumn Header="Age" CellTemplate="{StaticResource AgeDT}" />
<GridViewColumn Header="Skill" CellTemplate="{StaticResource SkillDT}" />
</GridView>
</ListView.View>
</ListView>
</Grid>
