将treeviewitem显示为wpf中的网格行

Question

基本上需要在wpf中使用treeview控件来实现这样的事情:(随机图片)

节点和子节点具有相同标头的位置.

我google了很多,但我对wpf的了解并不是那么好.

这是我的父节点类:

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

和孩子:

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

我的xaml树视图:

  <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>

我试过使用Grid但很明显它会创建不同的网格,所以我可以继续使用列宽.

我试过如何在wpf应用程序中使gridview成为treeview的子元素,但是他们使用了ListView.它现在不适合我,因为treeviewitem选择功能与我的树视图和后面的代码紧密结合.

有什么想法可以做到吗？谢谢.

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 = "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;

如果您的代码唯一的问题是每个树视图项目以不同的网格列宽度进行渲染，则可以尝试使用“共享大小范围”功能将它们全部对齐。在TreeView控件中，设置Grid.IsSharedSizeScope为true：

然后将s 添加SharedSizeGroup到ColumnDefinition所有树视图项目中应具有相同宽度的s（您的第一列定义无论如何都具有固定的宽度，因此不需要它）：-

<Grid.ColumnDefinitions>
   <ColumnDefinition Width="20" />
   <ColumnDefinition Width="Auto" SharedSizeGroup="A" />
   <ColumnDefinition SharedSizeGroup="B" />
</Grid.ColumnDefinitions>

这些值只是用于“命名”列的字符串，并且可以是您喜欢的任何内容。
