Question

我正在为应用程序构建用户个人资料页面。该页面允许用户查看和编辑基本数据字段（姓氏，名字等）。此外，还有一个与之链接的用户网格。用户应该能够在此网格上执行一些基本的CRUD操作。如何将此网格绑定到作为viewmodel的属性传递给视图的IEnumerable（或类似的）？

视图模型是这样的：

using System.Collections.Generic;

namespace Pricing.Models.ViewModel
{
    public class UserProfileUpdateViewModel
    {
        public int UserId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public IEnumerable<LinkedUserViewModel> LinkedUsers { get; set; }
    }
}

我的用户个人资料视图目前看起来如下所示。请注意第38行上的TODO注释，它标记了当前已损坏的内容。

@model Pricing.Models.ViewModel.UserProfileUpdateViewModel
<div class="panel-body">
    <h2>User Profile</h2>
    @using (Html.BeginForm("UpdateProfile", "Account", FormMethod.Post))
    {
        @Html.AntiForgeryToken()
        @Html.HiddenFor(profile => profile.UserId)
        <div class="form-horizontal">
            <div class="form-group">
                <label class="control-label col-md-2">Username</label>
                <div class="col-md-10" style="padding-top:7px">
                    @User.Identity.Name
                </div>
            </div>
        </div>
        <div class="form-horizontal">
            <div class="form-group">
                @Html.LabelFor(profile => profile.FirstName, "First Name", new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.EditorFor(profile => profile.FirstName, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(profile => profile.FirstName, "", new { @class = "text-danger" })

                    @Html.EditorFor(profile => profile.LastName, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(profile => profile.LastName, "", new { @class = "text-danger" })
                </div>

Answer 1

你应该传递IEnumerable而不是类型。

@(Html.Kendo().Grid<Model.LinkedUsers>()

将网格绑定到视图的视图模型中的IEnumerable
