所以我有一个这样的类结构
Store
Owner
Cashier
List of Products
Product Name
Price
List of Vendors
Company Name
Contact Name
所以有 4 个对象:Store、Person(Owner 和 Cashier)、Product 和 Vendor。
我想找到一种方法将此结构绑定到 XAML 树中,因此每个节点都代表此结构的一个对象,例如:

到目前为止,我只能使用一个顶级对象 -> 一个子对象来做到这一点。像这样:
Store
- Departmen 1 Products
Book 1
Book 2
Book 3
- Department 2 Products
Bike 1
Bike 2
Bike 3
所以这里的重要区别在于,在第一棵树中,子节点是 3 种不同类型的对象(Store 有 2 个 Person 对象,1 个 Product 和 1 个 Vendor 对象);而在第二种情况下,每个根节点只有一种类型的子节点(Store 有 Department,Department 有 Products)。
我已经使用 HierarchicalDataTemplates 完成了第二个示例,所以我认为这可以解决我的问题,但事实并非如此。关于我如何做到这一点的任何想法?下面是创建 Store 结构的代码:
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
this.DataContext = new List<Store>() { Store.CreateStore() };
}
}
public class Store
{
public string StoreName { get; set; }
public Person Owner { get; set; }
public Person Cashier { get; set; }
public List<Product> Products { get; set; }
public List<Vendor> Vendors { get; set; }
public Store()
{
this.Products = new List<Product>();
this.Vendors = new List<Vendor>();
}
public static Store CreateStore()
{
Store store = new Store();
// set name
store.StoreName = "Book store";
// set staff
store.Owner = new Person() { FirstName = "John", LastName = "Smith" };
store.Cashier = new Person() { FirstName = "Jane", LastName = "Smart" };
// add products
store.Products.Add(new Product() { Name = "Mechanical Pencil", Price = 1.25m});
store.Products.Add(new Product() { Name = "Pen", Price = 2.50m });
store.Products.Add(new Product() { Name = "WPF Book", Price = 28.94m });
store.Products.Add(new Product() { Name = "ASP.NET Book", Price = 29.50m });
// add vendors
store.Vendors.Add(new Vendor() { CompanyName = "Bic", ContactName = "Bill Gates" });
store.Vendors.Add(new Vendor() { CompanyName = "O'Reilly", ContactName = "Steve Jobs" });
return store;
}
}
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class Product
{
public string Name { get; set; }
public decimal Price { get; set; }
}
public class Vendor
{
public string CompanyName { get; set; }
public string ContactName { get; set; }
}
我想避免在代码端创建树结构。任何帮助将不胜感激。
