列表故障(UWP)
列表故障(UWP)
提问于 2016-10-29 20:18:42
我为UWP平台编写应用程序。
我在代码中使用了绑定。
下面是我的ViewModel的代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Diagnostics;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;
using Milano.Annotations;
using WooCommerceNET;
using WooCommerceNET.WooCommerce;
using Newtonsoft.Json;
namespace Milano.Classes
{
public class InWorkViewModel: INotifyPropertyChanged
{
private List<LineItem> productList;
public List<LineItem> ProductList
{
get { return productList; }
set { productList = value; OnPropertyChanged(); }
}
private List<RootObject> ordersList;
public List<RootObject> OrdersList
{
get { return ordersList; }
set { ordersList = value; OnPropertyChanged(); }
}
private RootObject ordersChange;
public RootObject OrdersChange
{
get { return ordersChange; }
set { ordersChange = value; OnPropertyChanged(); }
}
private LineItem ordersChange2;
public LineItem OrdersChange2
{
get { return ordersChange2; }
set { ordersChange2 = value;OnPropertyChanged(); }
}
public InWorkViewModel()
{
Inwork_down();
// var interval = 100000;
//UpdateWithImterwal(interval);
}
/* private async void UpdateWithImterwal(int interval)
{
// OrdersList.Clear();
Inwork_down();
await Task.Delay(interval).ContinueWith(_ => UpdateWithImterwal(interval));
}*/
public async void Inwork_down()
{
RestAPI rest = new RestAPI("http://simplegames.com.ua/wp-json/wc/v1/", "ck_9d64c027d2c5f81b8bed3342eeccc6d337be813d", "cs_60697b1e6cbdeb8d62d19e0765e339f8e3334754");
WCObject wc = new WCObject(rest);
//Get all products
var orders = await wc.GetOrders(new Dictionary<string, string>() {
{ "per_page", "100" }, { "status","processing"} }); // Dodelat filtr dlaya teh chto v rabote
string products = orders.ToFormattedJsonString();
Debug.WriteLine(products);
List<RootObject> rootObjectData = JsonConvert.DeserializeObject<List<RootObject>>(products);
OrdersList = new List<RootObject>(rootObjectData);
}
public event PropertyChangedEventHandler PropertyChanged;
[NotifyPropertyChangedInvocator]
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
public class Billing
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
public string email { get; set; }
public string phone { get; set; }
}
public class Shipping
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
}
public class LineItem
{
public int id { get; set; }
public string name { get; set; }
public string sku { get; set; }
public int product_id { get; set; }
public int variation_id { get; set; }
public int quantity { get; set; }
public string tax_class { get; set; }
public double price { get; set; }
public double subtotal { get; set; }
public double subtotal_tax { get; set; }
public double total { get; set; }
public double total_tax { get; set; }
public List<object> taxes { get; set; }
public List<object> meta { get; set; }
}
public class ShippingLine
{
public int id { get; set; }
public string method_title { get; set; }
public string method_id { get; set; }
public double total { get; set; }
public double total_tax { get; set; }
public List<object> taxes { get; set; }
}
public class RootObject
{
public int id { get; set; }
public int parent_id { get; set; }
public string status { get; set; }
public string order_key { get; set; }
public string currency { get; set; }
public string version { get; set; }
public bool prices_include_tax { get; set; }
public string date_created { get; set; }
public string date_modified { get; set; }
public int customer_id { get; set; }
public double discount_total { get; set; }
public double discount_tax { get; set; }
public double shipping_total { get; set; }
public double shipping_tax { get; set; }
public double cart_tax { get; set; }
public double total { get; set; }
public double total_tax { get; set; }
public Billing billing { get; set; }
public Shipping shipping { get; set; }
public string payment_method { get; set; }
public string payment_method_title { get; set; }
public string transaction_id { get; set; }
public string customer_ip_address { get; set; }
public string customer_user_agent { get; set; }
public string created_via { get; set; }
public string customer_note { get; set; }
public string date_completed { get; set; }
public string date_paid { get; set; }
public string cart_hash { get; set; }
public List<LineItem> line_items { get; set; }
public List<object> tax_lines { get; set; }
public List<ShippingLine> shipping_lines { get; set; }
public List<object> fee_lines { get; set; }
public List<object> coupon_lines { get; set; }
}我的问题出在哪里。
如你所见，我在类中有这个public List<LineItem> line_items { get; set; }。我需要从rootObject中获取这个列表，并像绑定RootObject一样绑定其中的值。
那么，什么是应用程序中的视图逻辑。我将一些数据绑定到左侧面板，当我点击左侧面板上的element时，我使右侧面板可见，在那里我从public RootObject OrdersChange绑定в属性。
以下是一些屏幕：
我怎么能做到这一点？

如果我理解正确的话，您希望将两个类绑定到一个视图。如果是这样，我可以建议两种方法: 1)为这两个类创建基类。
class BaseClass { }
class RootObject: BaseClass { }
class LineItem : BaseClass { }
class MainViewModel
{
public List<LineItem> ProductList { get; set; }
public List<RootObject> OrdersList { get; set; }
public BaseClass LeftListViewSelectedItem { get; set; }
}2)也可以将属性LeftListViewSelectedItem的返回类型设置为object。对于绑定来说，无论你返回什么都无关紧要。
