编辑视图发布错误的对象

如果我评论 <%:Html.TextBoxFor(model=>model.ListID)%> 第行,当我点击submit时,控制器不接收诸如name=“x”和listID=10的DSList,而是始终获取listID=0。

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DomainModel.Entities.DSList>" %>

    <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
        Edit
    </asp:Content>
    <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
        <h2>
            Edit</h2>
        <% using (Html.BeginForm())
           {%>
        <%: Html.ValidationSummary(true) %>
        <fieldset>
            <legend>Fields</legend>

            <div class="editor-field">
                <%--<%: Html.TextBoxFor(model => model.ListID) %>--%>
            </div>

            <div class="editor-label">
                <%: Html.LabelFor(model => model.Name) %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.Name) %>
                <%: Html.ValidationMessageFor(model => model.Name) %>
            </div>
            <p>
                <input type="submit" value="Save" />
            </p>
        </fieldset>
        <% } %>
        <div>
            <%: Html.ActionLink("Back to List", "Index") %>
        </div>
    </asp:Content>

控制器:

[HttpPost]
        public ActionResult Edit(DSList l)
        {
 // l always comes with the id equal to 0.
... logic ...
}

如何才能接收正确的对象?
