我有以下TreeView:
<Grid>
<TreeView Background="LightGoldenrodYellow" Grid.Row="3">
<TreeViewItem Header="Section 4">
<TreeViewItem>
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Total:" Width="150"/>
<TextBlock Text="{Binding Pool.Count}" />
</StackPanel>
</TreeViewItem.Header>
</TreeViewItem>
<TreeViewItem>
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Code" Width="150" />
<TextBlock Text="{Binding SecretViewModel.Codes}" />
</StackPanel>
</TreeViewItem.Header>
</TreeViewItem>
<TreeViewItem Header="Sub-Section 4.1">
<TreeViewItem>
<ListBox ItemsSource="{Binding Path=ListOfNames, UpdateSourceTrigger=PropertyChanged}" />
</TreeViewItem>
</TreeViewItem>
</TreeViewItem>
<TreeViewItem Header="Section 5">
<TreeViewItem>
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Color:" Width="150" />
<TextBlock Text="{Binding Colors}" />
</StackPanel>
</TreeViewItem.Header>
</TreeViewItem>
</TreeView>
</Grid>
如何替换Listbox并将ObservableCollection绑定到TreeviewItem?它看起来应该是分层。
我试图插入此代码而不是使用TextBox,但这不起作用:
<HierarchicalDataTemplate>
<HierarchicalDataTemplate.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=ListOfNames, UpdateSourceTrigger=PropertyChanged}"/>
</DataTemplate>
</HierarchicalDataTemplate.ItemTemplate>
</HierarchicalDataTemplate>

不太确定你到底要做的是什么。你的意思不是......
<TreeViewItem Header="Section 4">
<TreeViewItem Header="Sub-Section 4.1"
ItemsSource="{Binding Path=ListOfNames,
UpdateSourceTrigger=PropertyChanged}" />
</TreeViewItem>
