我正在从以下问题的答案中进行工作：Display treeviewitem as grid rows in wpf，而我正努力使要选择的树中的项目得到解决。您如何使用这种类型的代码呢？谢谢

我尝试制作TextBlocks和TextBoxes，但是没有运气。

<TreeView x:Name="treeviewList"  ItemsSource="{Binding ManufacturerList}">
            <TreeView.ItemTemplate>
                <DataTemplate>
                    <TreeViewItem  ItemsSource="{Binding Models}">
                        <TreeViewItem.Header>
                            <Grid Width="350">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="100"></ColumnDefinition>
                                    <ColumnDefinition Width="Auto" MinWidth="50"></ColumnDefinition>
                                    <ColumnDefinition ></ColumnDefinition>
                                </Grid.ColumnDefinitions>
                                <TextBlock Text="{Binding Task}" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="0"/>
                                <TextBlock Text="{Binding durationTotal}" Margin="10,10,0" HorizontalAlignment="Left" VerticalAlignment="Center"  Grid.Column="1"/>
                                <TextBlock Text="{Binding HeadNote}" HorizontalAlignment="Left"  VerticalAlignment="Center"  Grid.Column="2"/>
                            </Grid>
                        </TreeViewItem.Header>
                        <TreeViewItem.ItemTemplate>
                            <DataTemplate>
                                <Grid Margin="-20,0">
                                    <Grid.ColumnDefinitions>
                                        <ColumnDefinition Width="100"></ColumnDefinition>
                                        <ColumnDefinition Width="Auto" MinWidth="50"></ColumnDefinition>
                                        <ColumnDefinition></ColumnDefinition>
                                    </Grid.ColumnDefinitions>

                                    <TextBlock Text="{Binding SubTask}" Margin="10,0" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="0"/>
                                    <TextBlock Text="{Binding Duration}" Margin="10,0" HorizontalAlignment="Left" VerticalAlignment="Center"  Grid.Column="1"/>
                                    <TextBlock Text="{Binding Notes}" HorizontalAlignment="Left" VerticalAlignment="Center"  Grid.Column="2"/>
                                </Grid>
                            </DataTemplate>
                        </TreeViewItem.ItemTemplate>
                    </TreeViewItem>
                </DataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>

C＃代码

public class Company
{
    public string Task { get; set; }
    public string durationTotal { get; set; }
    public string HeadNote { get; set; }
    public List<Model> Models { get; set; }
}
public class Model
{
    public string SubTask { get; set; }
    public string Duration { get; set; }
    public string Notes { get; set; }      
}

List<Company> ManufacturerList = new List<Company>();

        ManufacturerList.Add(new Company()
        {
            Task = "Coding",durationTotal = "4",HeadNote = "Coding Task",Models = new List<Model>()
            {new Model(){SubTask = "Write",Duration = "2",Notes ="It pays the bills" },new Model(){SubTask = "Compile",Duration = "1",Notes ="c# or go home" },new Model(){SubTask = "Test",Notes ="works on my m/c" },}
        });


        ManufacturerList.Add(new Company()
        {
            Task = "Communicate",durationTotal = "2",HeadNote = "Communicate Task",Models = new List<Model>()
            {new Model(){SubTask = "Email",Duration = "0.5",Notes ="so much junk mail"  },new Model(){SubTask = "Blogs",Duration = "0.25",Notes ="blogs.msdn.com/delay" },new Model(){SubTask = "Twitter",Notes ="RT:nothing to report" },}
        });

        treeviewList.ItemsSource = ManufacturerList;
