MVC5 Asp.net有没有办法从EditorFor得到正确的值的子类 [英] MVC5 Asp.net Is there a way to get the correct value from EditorFor for a subclass

问题描述

我有一个类

 公共类公民
{
    众长ID {搞定;组; }
    公共字符串名称{;组; }
    众长CityID {搞定;组; }
    公共字符串城{搞定;组; }
    公开名单＆LT; CitizenResource＆GT;资源{搞定;组; }
}
 

我想编辑在资源的个别项目，但EditorFor没有建立正确输入。

  @for（INT I = 0; I＆LT; Model.Resources.Count;我++）
{
    @ Html.BeginForm（EditResource，公民）
    {
        @ Html.AntiForgeryToken（）
        ＆LT; D​​IV CLASS =形横＆GT;
            ＆LT; D​​IV CLASS =表单组＆GT;
                ＆LT; p =班的形式控制静电＆GT;
                    @ Html.DisplayFor（型号=＆GT; model.Resources [I] .Name点）
                ＆所述; / P＆GT;
                ＆LT; D​​IV CLASS =COL-MD-10＆GT;
                    @ Html.EditorFor（型号=＆GT; model.Resources [I] .CurrentAmount，新{htmlAttributes = {新@class =表格控}}）
                    @ Html.ValidationMessageFor（型号=＆GT; model.Resources [I] .CurrentAmount，新{@class =TEXT-危险}）
                    ＆LT;输入类型=隐藏的名字=资源ID值=@ Model.Resources [I] .ResourceID/＆GT;
                    ＆LT;输入类型=提交值=更新级=BTN BTN-默认的/＆GT;
                ＆LT; / DIV＆GT;
            ＆LT; / DIV＆GT;
        ＆LT; / DIV＆GT;
     }
}
 

我得到的是NAME =资源[0] .CurrentAmount然后没有正确映射到CitizenResource类。

谁能帮我指出了正确的方向？

解决方案

您发的原因的前pression该名称：

  

我得到的是NAME =资源[0] .CurrentAmount然后没有映射
  正确的CitizenResource类。

  @ Html.EditorFor（型号=＆GT; model.Resources [I] .CurrentAmount，新{htmlAttributes = {新@class =表格控}}）
 

相反，必须编辑CitizenResource的局部视图

  @model CitizenResource@using（Html.BeginForm（EditResource，公民））{
            {
//完整的元素
@ Html.EditorFor（型号=＆GT; model.CurrentAmount，新{htmlAttributes = {新@class =表格控}}）
//元件的其余部分
}}
 

I have a class

public class Citizen
{
    public long ID { get; set; }
    public string Name { get; set; }
    public long CityID { get; set; }
    public string City { get; set; }
    public List<CitizenResource> Resources { get; set; }
}

I want to edit individual items in the Resources but the EditorFor doesn't set up the input correctly.

@for (int i = 0; i < Model.Resources.Count; i++ )
{ 
    @Html.BeginForm("EditResource", "Citizen")
    {
        @Html.AntiForgeryToken()
        <div class="form-horizontal">
            <div class="form-group">
                <p class="form-control-static">
                    @Html.DisplayFor(model => model.Resources[i].Name)
                </p>
                <div class="col-md-10">
                    @Html.EditorFor(model => model.Resources[i].CurrentAmount, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Resources[i].CurrentAmount, "", new { @class = "text-danger" })
                    <input type="hidden" name="ResourceID" value="@Model.Resources[i].ResourceID"/>
                    <input type="submit" value="Update" class="btn btn-default" />
                </div>
            </div>
        </div>
     }
}

What I get is name="Resources[0].CurrentAmount" which then doesn't map correctly to the CitizenResource class.

Can anyone help point me in the right direction?

解决方案

The expression you sent causes that name:

What I get is name="Resources[0].CurrentAmount" which then doesn't map correctly to the CitizenResource class.

@Html.EditorFor(model => model.Resources[i].CurrentAmount, new { htmlAttributes = new { @class = "form-control" } })

Instead have a partial view to edit an CitizenResource

@model CitizenResource

@using(Html.BeginForm("EditResource", "Citizen")){
            {
//The complete elements
@Html.EditorFor(model => model.CurrentAmount, new { htmlAttributes = new { @class = "form-control" } })
//The rest of the elements
}}
