MVC4如何在父视图点击提交时获取部分视图中的数据

我为用户更新数据创建了一个编辑页面，父视图显示一些书籍详细信息，部分视图是一个循环显示每本书的状态。此外，父视图有一个提交按钮，用于更新部分视图和父视图，但是当我单击提交时，只有父视图数据可以更新，部分视图仍然没有更新。下面的代码：

型号：

public class LibraryInventory

      public decimal LibraryID  get; set; 
      public string Title  get; set; 
      public List<LibraryItem> Entities  get; set; 


public class LibraryItem
     public decimal StatusID  get; set; 
      public string Location  get; set; 
      public decimal BorrowedBy  get; set; 

控制器：

public ActionResult EditRecord(string ID)
    
     DataTable dt = (DataTable)Session["EditGridData"];
     LibraryInventory record = new LibraryInventory(dt.Rows[0]);
     dt = LibraryEditBLL.GetEditItems(ID);
     if (results.ToList().Count > 0)
     
          record.Entities = LibraryItem.ConvertToLibraryEntity(dt).ToList();
     
     return View(record);



[HttpPost]
public ActionResult EditRecord(string FormButton, LibraryInventory model)
   
     switch (FormButton)
         
       case "Submit":                    
           if (ModelState.IsValid)
                  
               LibraryEditBLL.UpdateInventoryLibrary(model);
           
           return View("EditRecord",record);
      default:
           return RedirectToAction("Edit"); //other page not need check
 

查看：

 @model XXX.Models.LibraryModels.LibraryInventory                             
 @using (html.BeginForm("EditRecord", "Library", FormMethod.Post, new  enctype = "multipart/form-data" ))
 @Html.HiddenFor(m =>m.LibraryID)
 <table>
     <tr>
        <td>@Html.TextBoxFor(m => m.Title)</td> 
        @for (var i = 0; i < @Model.Entities.Count; i++)
        
            @Html.Partial("EditItem", @Model.Entities[i])

        
     </tr>
 </table>
  




  @model XXX.Models.LibraryModels.LibraryItem
  <tr>
      <td> @Html.DropDownListFor(m => m.StatusID) </td>
      <td> @Html.DropDownListFor(m => m.Location)</td>
      <td> @Html.DropDownListFor(m => m.BorrowedBy) </td>
  </tr>

【参考方案1】：

试试这个代码以获得你的观点。对于这个简单的场景，不需要局部视图。

@model XXX.Models.LibraryModels.LibraryInventory                             
@using (Html.BeginForm("EditRecord", "Library", FormMethod.Post, new  enctype = "multipart/form-data" ))
@Html.HiddenFor(m =>m.LibraryID)
<table>
 <tr>
    <td>@Html.TextBoxFor(m => m.Title)</td> 
 </tr>
    @for (var i = 0; i < Model.Entities.Count; i++)
              
     <tr>
         <td> @Html.DropDownListFor(m => Model.Entities[i].StatusID) </td>
          <td> @Html.DropDownListFor(m => Model.Entities[i].Location)</td>
            <td> @Html.DropDownListFor(m => Model.Entities[i].BorrowedBy) </td>

     </tr>
