List 中的模型项绑定

Question

我已经将模型传递给局部视图，然后我需要将一些文本字段绑定到视图中的模型。

@model SRINews.Domain.NewsTotal

@using (Html.BeginForm("UpdateNewsItem", "Home", FormMethod.Post))

{

    <table class="table table-borderless table-cart" id="mytable" data-addclass-on-smdown="table-sm">

        <tbody>

            @foreach (var item in Model.items)

            {

                <tr class="newsRow" id="@item.ItemId">

                    <td class="cart-img nostretch">

                        <a href="#"><img src="@item.ImageUrl" alt=""></a>

                    </td>

                    </tr>

                    <tr>

                    <td>

                     <input type="text" class="form-control" placeholder="Personalized Name">

                     //@Html.TextboxFor(x=>x)

                     // I want to bind PersonalizedName to model

                    </td>

                    </tr>

                    <tr>

                    <td>

                     <input type="text" class="form-control" placeholder="Country">

                      // I want to bind Country to model

                    </td>

                    </tr>

                    }

                    </tbody>

                    </table>

                       <input type="submit" class="btn btn-primary" value="Personal Details" />

}

模型

 public class Items

    {

        public int ItemId { get; set; }

        public string ItemCode { get; set; }

        public string PersonalizedName {get;set;}

        public string Country {get;set;}

    }

    public class NewsTotal

    {

        public int BaseItem { get; set; }

        public string BaseName {get;set;}

        public List<Items> items { get; } = new List<Items>();

    }

Public ActionResult UpdateNewsItem(NewsTotal nTotal)

{

return View();

}

您想使用传统的 for 循环，因此您可以使用索引绑定到List<T>模型中的您，您还需要使其items可变，因此您还需要有一个setfor 它，否则您将不会能够提交任何东西：//You'll need to make this mutable, so it can post the edited valuespublic List<Items> items { get; set; } = new List<Items>();然后在您的视图中：@for(int i = 0; i < Model.items.Count; i++){&nbsp; &nbsp;@Html.HiddenFor(x => Model.items[i].ItemId)&nbsp; &nbsp;@Html.HiddenFor(x => Model.items[i].ItemCode)&nbsp; &nbsp;<tr class="shoppingCartRow" id="@Model.items[i].ItemId">&nbsp; &nbsp; &nbsp;<td class="cart-img nostretch">&nbsp; &nbsp; &nbsp; &nbsp;<a href="#"><img src="@Model.items[i].ImageUrl" alt=""></a>&nbsp; &nbsp; &nbsp;</td>&nbsp; &nbsp;</tr>&nbsp; &nbsp;<tr>&nbsp; &nbsp; &nbsp;<td>&nbsp; &nbsp; &nbsp; &nbsp;@Html.TextboxFor(x=> Model.items[i].PersonalizedName, new { @placeholder = "Personalized Name"})&nbsp; &nbsp; &nbsp;</td>&nbsp; &nbsp;</tr>&nbsp; &nbsp;<tr>&nbsp; &nbsp; &nbsp;<td>&nbsp; &nbsp; &nbsp; &nbsp;@Html.TextboxFor(x=> Model.items[i].Country, new { @placeholder = "Country"})&nbsp; &nbsp; &nbsp;</td>&nbsp; &nbsp;</tr>}
