asp.net的MVC模型绑定失败＆LT;列表＆gt;在编辑模板项目 [英] asp.net mvc model binding fails for <List> items in editor template

问题描述

我搜索的SO，仍然不知道我做错了这里的许多职位。我有一个模式的订单，其中包括一个＆LT;列表＆gt; OrderItem的的

I've searched many posts on SO and still not sure what I did wrong here. I have a model for "Order" which includes a <list> of "OrderItem"

public class Order
{
    public int OrderId { get; set; }
    public int CustId { get; set; }
    public DateTime OrderDate { get; set; }
    public int OrderType { get; set; }
    ...
    ...
    public List<OrderItem> OrderItems = new List<OrderItem>();
}
public class OrderItem
{
    public string ProductCode { get; set; }
    public decimal RetailPrice { get; set; }
    public string ProductQuantity { get; set; }
}

在我看来，这是强类型的订单模式，我使用的是编辑模板显示订单项

In my view, which is strongly typed to the Order model, I am using an Editor Template to display the order items

@model FTG.Models.Order
@Html.EditorFor(x => x.OrderItems)

和编辑模板，似乎为模型绑定发生指定一个合适的名称：

and the editor template seems to assign a proper name for the model binding to occur:

input  type="number" id="OrderItems_0__ProductQuantity" name="OrderItems[0].ProductQuantity"...
input  type="number" id="OrderItems_1__ProductQuantity" name="OrderItems[1].ProductQuantity"...

但我的模型回来控制器与计数= 0 的名单。该模型的其余看起来不错，我只是不能从的OrderItems列表中获取值。

But my model comes back to the controller with count=0 for the list. The rest of the model looks fine, I just can't get the values from the list of orderitems.

有谁知道我做错了，或者什么，我缺少什么？

Does anyone know what I am doing wrong, or what I am missing?

推荐答案

我觉得你的模型类是缺少对孩子列表中的属性。尝试添加属性的列表的OrderItems

I think your model class is missing a property for the child list. Try adding a property for the OrderItems list.
