我想创建一个带有样式的 MasterDetails TreeView。

从这个问题我想重用切换按钮

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">
                        <Setter Property="Data"
                  TargetName="ExpandPath"
                  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}" />
            </Style>


            <ControlTemplate TargetType="{x:Type TreeViewItem}" x:Key="selectedItemTemplate">

                <Grid Height="Auto">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"></RowDefinition>
                        <RowDefinition Height="Auto"></RowDefinition>
                        <RowDefinition Height="Auto"></RowDefinition>
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>

                        <ColumnDefinition Width="Auto"></ColumnDefinition>
                    </Grid.ColumnDefinitions>

                    <ToggleButton x:Name="toggleButton" Height="20" Width="20" Style="{StaticResource toggleButtonStyle}" />
                    <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Id}"></TextBlock>

                </Grid>
            </ControlTemplate>
        </Grid.Resources>

        <TreeView Height="Auto" 
                  HorizontalAlignment="Stretch" 
                  Margin="10" 
                  VerticalAlignment="Stretch" 
                  Width="Auto"
                  ItemsSource="{Binding Items}">
            <TreeView.ItemContainerStyle>

                            <ColumnDefinition Width="100*" />
                            <ColumnDefinition Width="100*" />
                        </Grid.ColumnDefinitions>

                        <TextBlock Grid.Column="0" Text="{Binding Id}"></TextBlock>
                        <TextBlock Grid.Column="1" Text="----"></TextBlock>
                        <TextBlock Grid.Column="2" Text="{Binding Name}"></TextBlock>
                    </Grid>

                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>
    </Grid>
</Window>

请原谅 XAML 的大块，但我真的不知道异常来自哪里。

但是现在我得到了一个没有更多信息的 StaticResourceHolder 异常。我只知道它与ToggleButton 有关。

所以，有两个问题：

  1. 如何了解有关我的 XAML 有什么问题的更多信息？

  2. XAML 有什么问题？

这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; }
    }
