效果如图
数据结构
public class DisplayViewModel
{
public string Name { get; set; }
public ListChildren { get; set; }
}前端TreeView通过ItemTemplate为其子级设置样式
设置数据源
Listvm = new List();
DisplayViewModel oneData = new DisplayViewModel() { Name="1", Children=new List()};
oneData.Children.Add(new DisplayViewModel() { Name = "1-1", Children = new List()
{
new DisplayViewModel(){Name="1-1-1",Children=new List()}
}
});
oneData.Children.Add(new DisplayViewModel()
{
Name = "1-2",
Children = new List()
{
new DisplayViewModel(){Name="1-2-1",Children=new List()
{
new DisplayViewModel(){Name="1-2-1-2",Children=new List()}
}
}
}
});
vm.Add(oneData);
vm.Add(new DisplayViewModel() { Name = "2", Children = new List() });
treeView.ItemsSource = vm;
