如何更改用于 GridViewColumn 的 CellTemplate 的数据模板

如何更改用于GridView列的CellTemplate的数据模板想要更改为其他数据模板，以便用户只能在选择特定行并且焦点位于文本框上时编辑第一列的值

我创建了一个示例应用程序来重现该问题。

下面是 xaml 文件中的代码：

<Window x:Class="WpfApplication1.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"
        xmlns:local="clr-namespace:WpfApplication1">
    <Window.Resources>
        <Style TargetType="{x:Type TextBox}" >
            <Setter Property="BorderThickness" Value="0"/>
            <Style.Triggers>
                <Trigger Property="IsFocused" Value="True">
                    <Setter Property="IsReadOnly" Value="False" />
                </Trigger>
                <Trigger Property="IsFocused" Value="False">
                    <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}, Path=Background}"/>
                    <Setter Property="IsReadOnly" Value="True" />
                </Trigger>
                <Trigger Property="IsReadOnly" Value="False">
                    <Setter Property="Background" Value="White"/>                    
                </Trigger>
            </Style.Triggers>
        </Style>
        <DataTemplate x:Key="DefaultTemplate">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Name}"/>
            </StackPanel>
        </DataTemplate>
        <DataTemplate x:Key="EditableTemplate">
            <StackPanel Orientation="Horizontal">
                <TextBox Text="{Binding Name}"/>
            </StackPanel>
        </DataTemplate>
        <Style x:Key="ListViewStyle" TargetType="{x:Type ListView}">
            <Setter Property="View">
                <Setter.Value>
                    <GridView >
                        <GridViewColumn Header="Name" CellTemplate="{StaticResource DefaultTemplate}"/>
                        <GridViewColumn Header="Age">
                            <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <StackPanel Orientation="Horizontal">
                                    <TextBlock Text="{Binding Age}"/>
                                </StackPanel>
                            </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                    </GridView>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <StackPanel>       
        <ListView x:Name="FoldersListView" Margin="3" SelectionMode="Single"  ItemsSource="{Binding Path=ObjectCollection}"                  
                         IsSynchronizedWithCurrentItem="True" Style="{StaticResource ListViewStyle}">
        </ListView>
     </StackPanel>
</Window>
