使用搜索关键字排序HTML表格？

Question

我有我的表正确显示，搜索和排序。但是，当我搜索关键字并在我的表格中显示记录并单击列标题进行排序时，搜索结果将被清除，并且我总是会将其带回原始页面，而不是对搜索结果进行排序。我不明白为什么会发生这种情况？任何帮助将不胜感激。谢谢

控制器：

public ActionResult ViewInventory(string owners, string keyword, string sortOrder) 
     { 
      ViewBag.OwnerSort = sortOrder == "owner_asce" ? "owner_desc" : "owner_asce"; 

      var records = from s in db.Assets select s; 
      switch (sortOrder) 
      { 
       case "owner_asce": 
        records = records.OrderBy(s => s.InventoryOwner); 
       break; 

       case "owner_desc": 
        records = records.OrderByDescending(s => s.InventoryOwner); 
       break; 
      } 
      return View(records.ToList()); 
} 

查看：

@model IEnumerable<CTS_Inventory.Models.Asset> 

@{ 
    ViewBag.Title = "View Inventory"; 
} 

<h2>View Inventory</h2> 


@using (Html.BeginForm()) 
{ 
    <p> 

     Keyword Search: @Html.TextBox("keyword") 

     <input type="submit" value="Search" /> 
    </p> 

    <table class="table" border="1"> 
     <tr> 
      <th> 
       @Html.ActionLink("owners","ViewInventory", new { sortOrder = ViewBag.OwnerSort}) 
      </th> 
     </tr> 

     @foreach (var item in Model) 
     { 
      <tr> 
       <td> 
        @Html.DisplayFor(modelItem => item.InventoryOwner) 
       </td> 
      </tr> 
     } 
    </table> 
}

排序时，您需要通过keyword参数也是如此。

首先，从动作传递给视图：

public ActionResult ViewInventory(string owners, string keyword, string sortOrder) 
{ 
    ViewBag.OwnerSort = sortOrder == "owner_asce" ? "owner_desc" : "owner_asce"; 
    ViewBag.Keyword = keyword; 

    // ... 
} 

然后在您的视图：

<th> 
    @Html.ActionLink("owners","ViewInventory", new { sortOrder = ViewBag.OwnerSort, keyword = ViewBag.Keyword }) 
</th>
