Try this xaml

  <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="10,0,10,0" 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="-20,0,0,0">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="100"></ColumnDefinition>
                                <ColumnDefinition Width="Auto" MinWidth="50"></ColumnDefinition>
                                <ColumnDefinition></ColumnDefinition>
                            </Grid.ColumnDefinitions>
                            <TextBlock Text="{Binding SubTask}" Margin="10,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Column="0"/>
                            <TextBlock Text="{Binding Duration}" Margin="10,0,10,0" 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# code

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", Duration = "1", 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", Duration = "0.25", Notes ="RT:nothing to report" },}
        });

        treeviewList.ItemsSource = ManufacturerList;

Result

Problem

Basically in need to achieve something like this using treeview control in wpf: (random picture) (source: msdn.com) Where nodes and child nodes have same headers. I googled a lot, but my knowledge in wpf not that good. Here is my parent node class: ``` public class Parent : PropertyChangedBase { public string ParentName { get; set; } public BindableCollection<Child> Children { get; set; } } ``` And child: ``` public class Child : PropertyChangedBase { public string ChildName { get; set; } } ``` My xaml tree view: ``` <TreeView Grid.Row="0" Grid.Column="0" ItemsSource="{Binding Nodes}"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type projectModels:Parent}" ItemsSource="{Binding Children}"> <StackPanel> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="20"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> <ColumnDefinition></ColumnDefinition> </Grid.ColumnDefinitions> <CheckBox Grid.Column="2"></CheckBox> <TextBlock Grid.Column="1" Text="{Binding ParentName}"> </TextBlock> </Grid> </StackPanel> </HierarchicalDataTemplate> <DataTemplate DataType="{x:Type projectModels:Child}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding ChildName}"></TextBlock> </StackPanel> </DataTemplate> </TreeView.Resources> </TreeView> ``` I tried using `Grid` but obviously it create different grids, so I can relay on column width. I tried How to make gridview a child element of a treeview in wpf application , but they use `ListView`. It's not an option for me right now, as treeviewitem selection functionality is tightly coupled with my treeview and code behind. Any ideas how it can be done? Thanks.
