WPF treeview例子

以下是一个基于WPF的treeview树形多列用户控件的例子，你可以参考它来实现你自己的需求：

<Window x:Class="WpfTreeViewExample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TreeView ItemsSource="{Binding}">
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate ItemsSource="{Binding Children}">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock Text="{Binding Name}" Grid.Column="0"/>
                        <TextBlock Text="{Binding Description}" Grid.Column="1"/>
                    </Grid>
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>
    </Grid>
</Window>

public class TreeViewItem
{
    public string Name { get; set; }
    public string Description { get; set; }
    public ObservableCollection<TreeViewItem> Children { get; set; } = new ObservableCollection<TreeViewItem>();
}

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        var root = new TreeViewItem { Name = "Root", Description = "This is the root item" };
        root.Children.Add(new TreeViewItem { Name = "Child 1", Description = "This is the first child item" });
        root.Children.Add(new TreeViewItem { Name = "Child 2", Description = "This is the second child item" });

        DataContext = new ObservableCollection<TreeViewItem> { root };
    }
}
