我有一个输出树视图的代码，每个树视图都有一个复选框。是否可以重命名每个复选框以反映它所显示的内容。

<Grid>
   <TreeView ItemsSource="{Binding Source={StaticResource xmlData},XPath=//@Name}">
      <TreeView.ItemTemplate>
         <DataTemplate>
            <CheckBox Name="Check1">
               <TreeViewItem Header="{Binding XPath.}">
                  <StackPanel>
                     <ListView Grid.Row="2" Grid.Column="2" ItemsSource="{Binding XPath=..//@Foodname}">
                        <ListView.View>
                           <GridView>
                              <GridViewColumn Header="Selection">
                                 <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                       <CheckBox Name="Check"/>
                                    </DataTemplate>
                                 </GridViewColumn.CellTemplate>
                              </GridViewColumn>
                              <GridViewColumn>
                              </GridViewColumn>
                           </GridView>
                        </ListView.View>
                     </ListView>
                  </StackPanel>
               </TreeViewItem>
            </CheckBox>
         </DataTemplate>
      </TreeView.ItemTemplate>
   </TreeView>
</Grid>

<Foods>
    <UnhealthyFoods Name ="Candy"/>
        <Food Foodname = "MMs" >
        </Food>
        <Food Foodname = "Skittles" >
        </Food>
        <Food Foodname = "Starburst" >
        </Food>
    </UnhealthyFoods>
    <HealthyFoods>
        <FoodGroup1 Name ="Vegetables"/>
        <Food Foodname = "Spinach" >
            </Food>
            <Food Foodname = "Brocolli" >
            </Food>
            <Food Foodname = "Greens" >
            </Food>
    </FoodGroup1>
    </HealthyFoods>
    <HealthyFoods>
        <FoodGroup2 Name ="Fruits"/>
        <Food Foodname = "Apples" >
            </Food>
            <Food Foodname = "Pears" >
            </Food>
            <Food Foodname = "Cherries" >
            </Food>
    </FoodGroup2>
    </HealthyFoods>
</Foods>

这是xml数据，我不关心它是如何写的，我无法对它进行更改。
我尝试使用，但错误说“你不能在空值表达式上调用方法。

[System.Windows.RoutedEventHandler]$check_checked={param($sender,$e) write-host "testing"}

Check.AddHandler([System.Windows.Controls.Checkbox])::CheckedEvent,$check_checked)

所以为了好玩，我尝试在树视图中没有的不同位置创建另一个复选框，上面的代码确实工作了。
