层次数据结构WPF TreeListView

您可以为HierarchicalDataTemplate设置DataTrigger并具有不同的属性绑定。举个例子。 Please check this earlier answer in this thread just in case you need more ideas.

 <HierarchicalDataTemplate  DataType="{x:Type local:Person}" ItemsSource="{Binding People}" >
    <Grid>
      <TextBlock x:Name="fName" Text="{Binding FirstName}"/>
      <TextBlock x:Name="lName" Text="{Binding LastName}" Visibility="Collapsed"/>
   </Grid>
   <HierarchicalDataTemplate.Triggers> 
    <DataTrigger Binding="{Binding State}" Value="A">
      <Setter TargetName="fName" Property="Visibility" Value="Collapsed"/>
       <Setter TargetName="lName" Property="Visibility" Value="Visible"/>
    </DataTrigger>
  </HierarchicalDataTemplate.Triggers> 
</HierarchicalDataTemplate>

如果父对象和子对象是不同的对象类型,则有一个非常简单的答案:只需在ResourceDictionary中使用多个HierarchicalDataTemplates:

<TreeView ItemsSource="{Binding Parents}">

  <TreeView.ResourceDictionary>

    <HierarchicalDataTemplate
        TargetType="{x:Type my:ParentType}"
        ItemsSource="{Binding Children}">

      ... parent content ...

    </HierarchicalDataTemplate>

    <HierarchicalDataTemplate
        TargetType="{x:Type my:ChildType}"
        ItemsSource="{Binding Children}">

      ... child content ...

    </HierarchicalDataTemplate>

  </TreeView.ResourceDictionary>
</TreeView>

这项技术并不适用于所有场景,但当它工作时,它是非常强大和富有表现力的。

ItemTemplateSelector 那叫 LoadResource() 加载适当的 HierarchicalDataTemplate
