Question

Ola.. I have a problem with editing of few models in table. I have a List of models on page (with foreach), something like

<table id="grid-table" >

@foreach (var image in ViewBag.Images)
{
    <tr>

        <td >
            <a href="@Url.Action("ShowFullImage", new { id = @image.ID })" rel="lightbox[roadtrip]" title="@image.Description" >
                <img src="@Url.Action("ShowImageThumbneil", new { id = @image.ID })" alt="@image.AlternateText" />
            </a>
        </td>

        <td >
            @using (Html.BeginForm("SaveImageInfo", "Admin", FormMethod.Post))
            {
                @Html.TextAreaFor(m => m.Description) <br />
                @Html.TextBoxFor(m => m.AlternateText) <br />
                @Html.LabelFor(m => m.ID)

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

    </tr>
}

and I want to have a way to edit ONE model item. In controller I have something like this:

    [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();
    }

but, of course, it’s not works..
Can somebody help me?

Answer 1

Change @Html.LabelFor(m => m.ID) with @Html.HiddenFor(m => m.ID). Contents of labels are not sent with POST, but contents of hidden fields are..
