内联模型编辑器MVC3。再次

Question

吾友.. 我还有一个麻烦。 愚蠢可能，但我看不出，有什么不对。

    public ActionResult Images(Guid? id)
    {
        ViewBag.Gallery = _core.GetGalleryByID(_client, (Guid)id);

        List<ImageModel> models = new List<ImageModel>();

        foreach (var img in _core.GetImagesByGalleryID(_client, (Guid)id))
        {
            ImageModel model = new ImageModel(_client);
            model.Thumbneil = img.Thumbneil;
            model.Description = img.Description;
            model.AlternateText = img.AlternateText;
            model.GalleryID = img.GalleryID;
            model.ID = img.ID;
            models.Add(model);
        }

        ViewBag.Images = models;
        return View();
    }

    [HttpPost]
    public ActionResult SaveImageInfo(ImageModel imageModel)
    {
        Image img = _core.GetImageByID(_client, imageModel.ID);
        img.AlternateText = imageModel.AlternateText;
        img.Description = imageModel.Description;

        _core.SaveImageInfo(_client, img);
        return View();
    }

这是控制器的一部分。 这是观点的一部分：

@model WebUI.Models.ImageModel
@{
    ViewBag.Title = "Images";
    Layout = "~/Views/Admin/_Layout.cshtml";
}

<h2>@ViewBag.Gallery.Name</h2>

<table id="grid-table" >

    @foreach (var image in ViewBag.Images)
    {
    <tr>
        ....
        <td >
            @using(Html.BeginForm("SaveImageInfo", "Admin", FormMethod.Post))
            {
                @Html.HiddenFor(m => m.ID)
                @Html.TextAreaFor(m => m.Description) <br />
                @Html.TextBoxFor(m => m.AlternateText) <br />

                <div id="item-post" >
                    <input title="Подтвердить" type="submit" value="Подтвердить" />
                </div>
            }
        </td>

    </tr>
    }

</table>

模特：

    public class ImageModel
{
    public Byte[] Thumbneil { get; set; }

    [Required]
    public String Description { get; set; }

    [Required]
    public Guid GalleryID { get; set; }

    [Required]
    public String AlternateText { get; set; }

    [Required]
    public Guid ID { get; set; }
}

在ActionResult中，SaveImageInfo（ImageModel imageModel）我应该有2个Guid：ID和GalleryID。但。 我有这个： 这是我的问题：为什么？我看不到......

在我看来，你需要在视图中为GalleryId添加一个HiddenFor：

@ Html.HiddenFor（m =＆gt; m.GalleryId）
