Question

我有带文本输入，表格和寻呼机的页面。文本输入用于设置每页的表行数。

查看代码：

    @using (Html.BeginForm("Index", "Read", FormMethod.Get))
    {
        <p>
            Rows per page: @Html.TextBox("cnt", ViewBag.cnt as int?)  
            <input type="submit" value="Refresh" />
        </p>
    }
    <table>
            <tr>
                <th>
                   @Html.ActionLink("Code", "Index", new { Order = ViewBag.CodeSortParm, cnt = ViewBag.cnt })      
                </th>
                <th>
                   @Html.ActionLink("Description", "Index", new { Order = ViewBag.TextSortParm, cnt = ViewBag.cnt }) 
                </th>
            </tr>

     @foreach (var item in Model) { 
        <tr>
            <td>
                 @item.Code             
            </td>
            <td>
                 @item.Text 
            </td>
        </tr>
    } 
</table>
Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

@Html.PagedListPager( Model, page => Url.Action("Index", new { page, cnt = ViewBag.cnt, Order = ViewBag.CurrentSort }) )

控制器代码：

public ActionResult Index(string Order, int? page, int? cnt)
        {
            ViewBag.CurrentSort = Order;
            ViewBag.CodeSortParm = String.IsNullOrEmpty(Order) ? "Code_desc" : "";
            ViewBag.TextSortParm = Order == "Text" ? "Text_desc" : "Text";

            ViewBag.cnt = cnt;

            Tbl T = new Tbl();
            IQueryable<ErrCode> ErrCodes = T.GetErrCodes();

            switch (Order)
            {
                case "Code_desc":
                    ErrCodes = ErrCodes.OrderByDescending(x => x.Code);
                    break;
                case "Text":
                    ErrCodes = ErrCodes.OrderBy(x => x.Text);
                    break;
                case "Text_desc":
                    ErrCodes = ErrCodes.OrderByDescending(x => x.Text);
                    break;
                default:
                    ErrCodes = ErrCodes.OrderBy(x => x.Code);
                    break;
            }

            int pageSize = cnt ?? 3;
            int pageNumber = (page ?? 1);
            var onePageOfProducts = ErrCodes.ToPagedList(pageNumber, pageSize);
            return View(onePageOfProducts);
        }

当我按下“刷新”按钮时，它只传递给控制器Cnt值。但我也想传递Order值。我尝试这个变种： @Html.TextBox("cnt", ViewBag.cnt as int?, new { Order = ViewBag.CurrentSort }) 还有这个： Html.BeginForm("Index", "Read", FormMethod.Get, new { Order = ViewBag.CurrentSort }) 但它不起作用（不将Order param传递给Controller）。提交表单时将Order param传递给Controller的正确方法是什么？

唯一可以发布的是Form中的内容。因此，您可以放置@Html.Hidden("Order", ViewBag.CurrentSort)。这将发布订单值，但不会显示。

使用@ Html.TextBox帮助程序传递额外的GET参数
