问题描述

  

我真的试图从一个文本框中控制器传递价值。我谷歌这个问题。但没有得到这对我的作品的任何合适的解决方案。
  下面是我的控制器。
   WebProductController

 使用系统;
使用System.Collections.Generic;
使用System.Data这;
使用System.Data.Entity的;
使用System.Linq的;
使用的System.Web;
使用System.Web.Mvc;
使用DatabaseService_WebAPI.Models;命名空间DatabaseService_WebAPI.Controllers

在我的控制器我真的调用add（）方法。在行动导致它传递价值观的控制器，但没有通过文本框的值。当我尝试用

  @using（Html.BeginForm（添加，WebProductController，FormMethod.Post））
 

然后形式没有按 T承认我的方法，当我使用按钮，在我的形式发送数据。
我中号停留在了这个问题。但无解：（

解决方案

您控制器应该是这样的：

 公众的ActionResult添加（IList的＆LT; ShoppingItemModel＆GT;项目）{
      的foreach（在项目ShopingItemModel项）{
          如果（item.Id！= NULL）{
               ShopingItem shopingItem = service.GetById（item.Id）;
               ...添加项目到任何
          }
      }
 }
 

您ShoppingItemModel：

 公共类ShoppingItemModel {
     [需要]
     公共标识{获取;设置;}     [需要]
     公众金额{获取;集;}     ...
}
 

您查看（我跳过Java脚本）：

  @model的IList＆LT; ShoppingItemModel＆GT; ＆LT; H2＆GT;及片剂LT; / H＆GT;
 @using（Html.BeginForm（添加，WebProductController，FormMethod.Post））{
 @ Html.ValidationSummary（真） ＆LT;表＆gt;
  ＆所述; TR＆GT;
    ＆LT;第i个
        名称
    ＆LT; /第i
    ＆LT;第i个
        价钱
    ＆LT; /第i
    ...
    ＆LT;第i度＆lt; /第i
＆LT; / TR＆GT;@for（INT指数;指数＆LT; Model.Count;指数++）{  ＆所述; TR＆GT;
    ＆所述; TD＆GT;
        @ Html.HiddenFor（型号=＆GT;模型[指数] .ID）
        @ Html.DisplayFor（型号=＆GT;模型[指数] .Name点）
    ＆LT; / TD＆GT;
    ＆所述; TD＆GT;
        @ Html.DisplayFor（型号=＆GT;模型[指数]。价格）
    ＆LT; / TD＆GT;
    ＆所述; TD＆GT;
        @ Html.DisplayFor（型号=＆GT;模型[指数] .Batch）
    ＆LT; / TD＆GT;
    ...
    ＆所述; TD＆GT;
        @ Html.TextBoxFor（型号=＆GT;模型[指数] .Quantity）
    ＆LT; / TD＆GT;
  ＆LT; / TR＆GT;
}
＆LT; /表＆gt;
＆LT;输入类型=提交值=添加/＆GT;
}
 

这是不完整的解决方案。只是一个提示。

    @Html.ActionLink("Back to List", "Create")
</div>

In my controller i`m calling Add() method. in action result it is passing values in the controller but not passing the textbox value. when i try to use

@using (Html.BeginForm("Add", "WebProductController",FormMethod.Post))

Then the form doesnt recognize my method when i use button to sending data in my form. im stuck in this problem. but no solution:(

解决方案

Your Controller should look like:

 public ActionResult Add(IList<ShoppingItemModel> items){
      foreach(ShopingItemModel item in items){
          if (item.Id != null){
               ShopingItem shopingItem = service.GetById(item.Id);
               ... Add Item to whatever
          }
      }
 }

Your ShoppingItemModel:

public class ShoppingItemModel{
     [Required]
     public Id{get;set;}

     [Required]
     public Amount{get;set;}

     ...
}

Your View (I Skipped Java Script):

 @model IList<ShoppingItemModel>

 <h2>Tablets</h2>
 @using (Html.BeginForm("Add", "WebProductController",FormMethod.Post)) {
 @Html.ValidationSummary(true)

 <table>
  <tr>
    <th>
        Name
    </th>
    <th>
        Price
    </th>
    ...
    <th>Amount</th>
</tr>

@for(int index; index < Model.Count; index++) {

  <tr>
    <td>
        @Html.HiddenFor(model => model[index].Id)
        @Html.DisplayFor(model => model[index].Name)
    </td>
    <td>
        @Html.DisplayFor(model => model[index].Price)
    </td>
    <td>
        @Html.DisplayFor(model => model[index].Batch)
    </td>
    ...
    <td>
        @Html.TextBoxFor(model => model[index].Quantity)
    </td>
  </tr>
}   
</table>   
<input type="submit" value="Add" />
}

That is not the complete solution. Just a hint. Tobi
