C# 带切换按钮的TreeView MasterDetails

我想创建一个带有样式的MasterDetails树视图

从那时起，我想重复使用切换按钮

这是我的XAML

<Window x:Class="TreeViewMasterDetails.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:TreeViewMasterDetails" 
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.Resources>
            <ControlTemplate x:Key="toggleButtonTemplate" TargetType="ToggleButton">
                <Grid Width="15" Height="13" Background="Transparent">
                    <Path x:Name="ExpandPath"
              HorizontalAlignment="Left" 
              VerticalAlignment="Center" 
              Margin="1,1,1,1"
              Fill="{StaticResource GlyphBrush}"
              Data="M 4 0 L 8 4 L 4 8 Z"/>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsChecked"
                 Value="True">

                  Value="M 0 4 L 8 4 L 4 8 Z"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
            <Style x:Key="toggleButtonStyle" TargetType="ToggleButton">
                <Setter Property="Template" Value="{StaticResource toggleButtonTemplate}" />

请原谅XAML的大阻塞，但我真的不知道异常是从哪里来的

但是现在我得到了一个StaticResourceHolder异常，没有更多信息。 我只知道这和切换按钮有关

因此，有两个问题：

如何进一步了解XAML的问题

XAML有什么问题

以下是我的项目视图模型：

public class NodeViewModel : ViewModelBase
    {
        public string Id { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }

        public ObservableCollection<NodeViewModel> Children { get; set; }
    }

public类nodevewmodel:ViewModelBase
{
公共字符串Id{get；set；}
公共字符串名称{get；set；}
公共字符串说明{get；set；}
公共可观测集合子项{get；set；}
}

查看内部异常。它会告诉你更多的细节。我认为问题就在这里。

{StaticResource GlyphBrush}

@nakiya:你是对的，是GlyphBrush，非常感谢！但它的行为仍不像默认项（单击时展开，但显示详细信息）。可能有点复杂。也许你想提供你的评论作为回答，因为它帮助了我，我会接受它。
