c# - 将 XDocument 绑定(bind)到 TreeView - 属性不显示

Question

我尝试将 XDocument 绑定(bind)到 TreeView 控件。除属性外，一切正常。 #%*!$#@^% 不想出现:D

请帮助我修改该代码以使其工作:

<SolidColorBrush x:Key="xmlValueBrush" Color="Blue" />
<SolidColorBrush x:Key="xmAttributeBrush" Color="Red" />
<SolidColorBrush x:Key="xmlTagBrush" Color="DarkMagenta" />
<SolidColorBrush x:Key="xmlMarkBrush" Color="Blue" />

<DataTemplate x:Key="AttributeTemplate">
    <StackPanel Orientation="Horizontal"
            Margin="3,0,0,0"
            HorizontalAlignment="Center">
        <TextBlock Text="{Binding Path=Name}"
             Foreground="{StaticResource xmAttributeBrush}" FontFamily="Consolas" FontSize="8pt" />
        <TextBlock Text="=&quot;"
             Foreground="{StaticResource xmlMarkBrush}" FontFamily="Consolas" FontSize="8pt" />
        <TextBlock Text="{Binding Path=Value, Mode=TwoWay}"
             Foreground="{StaticResource xmlValueBrush}" FontFamily="Consolas" FontSize="8pt" />
        <TextBlock Text="&quot;"
             Foreground="{StaticResource xmlMarkBrush}" FontFamily="Consolas" FontSize="8pt" />
    </StackPanel>
</DataTemplate>

<HierarchicalDataTemplate x:Key="NodeTemplate">
    <StackPanel Orientation="Horizontal" Focusable="False">
        <TextBlock x:Name="tbName" Text="Root" FontFamily="Consolas" FontSize="8pt" />
        <ItemsControl
            ItemTemplate="{StaticResource AttributeTemplate}" HorizontalAlignment="Center"
            ItemsSource="{Binding Path=Attributes}">
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
        </ItemsControl>
    </StackPanel>
    <HierarchicalDataTemplate.ItemsSource>
        <Binding Path="Elements" />
    </HierarchicalDataTemplate.ItemsSource>
    <HierarchicalDataTemplate.Triggers>
        <DataTrigger Binding="{Binding Path=NodeType}" Value="Text">
            <Setter TargetName="tbName" Property="Text" Value="{Binding Path=Value, Mode=TwoWay}" />
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
            <Setter TargetName="tbName" Property="Text" Value="{Binding Path=Name}" />
        </DataTrigger>
    </HierarchicalDataTemplate.Triggers>
</HierarchicalDataTemplate>

我的 TreeView:

<TreeView x:Name="XmlTree" Grid.Row="1"
      ItemsSource="{Binding Path=Root.Elements, UpdateSourceTrigger=PropertyChanged}"
      ItemTemplate="{StaticResource NodeTemplate}"
      SelectedItemChanged="XmlTree_SelectedItemChanged" />

这是我的代码:

private void BindXmlData(string filePath)
{
    _xml = XDocument.Load(filePath);
    XmlTree.DataContext = _xml;
}

所有节点都显示良好，但我无法通过属性使它们可见

您可以更改您的 DataTriggers 部分:

            <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
                <Setter TargetName="tbName" Property="Text" Value="{Binding Path=Name}" />
            </DataTrigger>

收件人:

            <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
                <Setter TargetName="tbName" Property="Text" Value="{Binding Path=Name.LocalName}" />
            </DataTrigger>
