显示树型视图在WPF网格行 [英] Display treeviewitem as grid rows in wpf

问题描述

基本上在需要实现像在WPF中使用这个TreeView控件：（随机图片）

Basically in need to achieve something like this using treeview control in wpf: (random picture)

在哪里节点和子节点具有相同的头。

Where nodes and child nodes have same headers.

我GOOGLE了很多，但我在WPF知识并不好

I googled a lot, but my knowledge in wpf not that good.

下面是我的父节点类：

 public class Parent : PropertyChangedBase
    {
        public string ParentName { get; set; }
        public BindableCollection<Child> Children { get; set; }
    }

和子：

public class Child : PropertyChangedBase
{
    public string ChildName { get; set; }
}

我的XAML树视图：

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>

我试着用电网但显然它创建不同电网，这样我就可以在中继列宽。

I tried using Grid but obviously it create different grids, so I can relay on column width.

我试过的如何让GridView控件在WPF应用程序一个树状的子元素，但他们使用的ListView 。这不是我的选择，现在，作为树型视图选择功能是紧密结合我的TreeView和后面的代码耦合的。

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.

任何想法如何可以做到？谢谢你。

Any ideas how it can be done? Thanks.

试试这个
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＃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 = "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",

            {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;
