如果复选框是从数据动态创建的，如何分配和访问WPF复选框的Name属性？

I have a TreeView and there are multiple layers to the TreeView using HierarchicalDataTemplates. Each TreeViewItem currently displays the "name" of the object that it represents. I now need to add CheckBoxes to the children of the tree which I have figured out somewhat, but I haven't figured out to access the NAME of the checkbox when it is checked.

我有一个TreeView，使用HierarchicalDataTemplates有多个TreeView层。每个TreeViewItem当前显示它所代表的对象的“名称”。我现在需要将CheckBoxes添加到我已经想到的树的子项中，但是在检查时我还没想过要访问该复选框的NAME。

To be more specific, I need the name of the checkbox that is checked because I need to apply a filter to some data accordingly. How do I access the name of each CheckBox when it is checked if the CheckBox and Name of the object for the TreeViewItem are created dynamically from data?

更具体地说，我需要选中复选框的名称，因为我需要相应地对某些数据应用过滤器。当检查TreeViewItem对象的CheckBox和Name是否是从数据动态创建时，如何访问每个CheckBox的名称？

i'm assuming you have a corresponding command in your viewmodel which all the checkbox items in the tree are bound to.

我假设你的viewmodel中有一个相应的命令，树中的所有复选框项都绑定到该命令。

bind to a command and send to current name of the ComboBoxItem as a CommandParameter

绑定到命令并作为CommandParameter发送到ComboBoxItem的当前名称

  <DataTemplate x:Key="ListBoxItemTemplate" DataType="{x:Type ListBoxItem}">
        <CheckBox Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListBox}, 
                  Path=DataContext.CheckBoxItemCheckedCommand}"
                  CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=Name}"/>                       
   </DataTemplate>
