Question

我有以下视图，主要查看项目列表作为显示： -

        @foreach (var item in Model.Resources) {
            <tr>
                 <td>
                    @Html.DisplayFor(modelItem => item.SystemInfo.MODEL)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.RESOURCENAME)
                </td>
                <td>

                     @Html.DisplayFor(modelItem  => item.ResourceLocation.SiteDefinition.AccountDefinition.SDOrganization.NAME)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.ResourceLocation.SiteDefinition.SDOrganization.NAME)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.ComponentDefinition.COMPONENTNAME)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.ResourceState.STATEDESC)
                </td>
                 <td id = "@item.RESOURCEID">

        @using (Ajax.BeginForm("CreateOn","VirtualMachine", new AjaxOptions {
         InsertionMode = InsertionMode.Replace,
         UpdateTargetId = item.RESOURCEID.ToString() ,
         LoadingElementId = "progress",
         HttpMethod = "POST"})){
 <span class="f">Hypervisor Server</span>

             @Html.DropDownListFor(model =>model.VirtualMachine.ServerID, ((IEnumerable<t.Models.Server>)ViewBag.Servers).Select(option => new SelectListItem {
                Text = (option == null ? "None" : option.Technology.Tag), 
                Value = option.ServerID.ToString(),
                Selected = (Model != null) && (Model.VirtualMachine != null) && (option.ServerID == Model.VirtualMachine.ServerID)
            }), "Choose...")
    @Html.ValidationMessageFor(model =>model.VirtualMachine.ServerID)
    @Html.Hidden("IT360id", item.RESOURCEID)
            @Html.Hidden("CustomerName",item.ResourceLocation.SiteDefinition.AccountDefinition.SDOrganization.NAME)
            @Html.Hidden("SiteName",item.ResourceLocation.SiteDefinition.SDOrganization.NAME)
            @Html.Hidden("ResourceName",item.RESOURCENAME)
         <input type="submit" value="Add To" class="btn btn-primary"/>
        }

但是用户可以使用ajax.beginform读取数据并选择在我们的数据库上创建项目。但要这样做，我需要将DisplayFor的一些值传递给模型绑定器。目前我已将所有需要的数据添加为隐藏字段，然后我将这些值传递给我的操作方法，如下所示： -

[HttpPost]
        public ActionResult CreateOn(VirtualMachineOnIT360Only vm, long IT360id, string CustomerName, string SiteName, string ResourceName)
        {

我发现我的方法不太可靠，我试图找出一个更可靠的解决方案。那么有人可以提出建议吗？感谢

要发布DisplayFor，我更喜欢使用hiddenfor而不是像这样隐藏：

            @Html.HiddenFor(item => item.RESOURCENAME);

将DisplayFor的值传递给模型绑定器
