InitializeComponent();
ObservableCollection<A> a = new ObservableCollection<A>();
a.Add(new A());
a[0].name = "thy";
ObservableCollection<AB> ab = new ObservableCollection<AB>();
ab.Add(new AB());
ab[0].abc = "38";
a[0].ab = ab;
Tree.DataContext = a;
}

class A
{
public string name { get; set; }

<Grid>
<TreeView x:Name="Tree" ItemsSource="{Binding}">
<TreeView.Resources>
<DataTemplate x:Key="aTemplate" DataType="{x:Type src:AB}">
<TextBox Text="{Binding Path=abc}" />
</DataTemplate>
</TreeView.Resources>
<TreeView.ItemTemplate>
<HierarchicalDataTemplate DataType="{x:Type src:A}"
ItemsSource="{Binding Path=ab}"
ItemTemplate="{StaticResource aTemplate}">
<TextBox x:Name="NameBox" Width="160" Text="{Binding Path=name}"/>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
</Grid>
</Window>
var container = Tree.ItemContainerGenerator.ContainerFromItem(Tree.Items[0]) as FrameworkElement;可惜还是不行。哎，等神人出现了
var textBox = Tree.ItemTemplate.FindName("NameBox", container) as TextBox;
System.Diagnostics.Debug.WriteLine(textBox);
