如果我理解了你的问题，那么传递给查看“模型”和下拉列表中使用的其他内容列表的答案可以通过以下代码完成：

控制器

         ....
         var model = service.GetMyThing(id);
         var genderList= service.GetGenders().Select(p => 
                   new SelectListItem { Value = p.Id.ToString(), Text = p.Name }).ToList();
         ViewBag.GenderList = genderList; 
         return View(model);

查看

         ....
         @Html.DropDownList("GenderId",(IEnumerable<SelectListItem>)ViewBag.GenderList)
         ....
          <div class="regi-field-set">
               @Html.TextBoxFor(model => model.DOB, new { @class = "jq_watermark", placeholder = "date of birth", tabindex = "8",id = "DOB",title = "please enter date of birth" })
               <div id="disableasterisk7"><span class="required">*</span></div>
              <div class="clear"></div>
              @Html.ValidationMessageFor(model => model.DOB)
          </div>

注意：这不是唯一的解决方案，自定义HTMLHelpers可用于绘制组合。

使用ajax你可以做到这一点：不要使用表格＆amp;在标签中声明您的属性：

<a href="someLink">@Model.idText</a>
<input type="text" id="textValue"/>
<input type="submit" id="btnSubmit"/>

jquery的：

 $(function (e) {
        //    Insert
        $("#btnSubmit").click(function () {

            $.ajax({
                url: "some url path",
                type: 'POST',
                data: { textField: $('#textValue').val(), idField: '@Model.idText' },
                success: function (result) {
                    //some code if success
                },
                error: function () {
                    //some code if failed
                }
            });
            return false;
        });
      });
