Question

我的模型看起来像这样：

public class UserAdminEditViewModel
{
    public User User { get; set; }
    public IEnumerable<Usergroup> Usergroups { get; set; }
    public IList<int> UsergroupID { get; set; }

    public UserAdminEditViewModel() {}
}

我的视图看起来像这样：

“％＆gt; USEREDIT

USEREDIT

<% using (Html.BeginForm()) {%>

    <fieldset>
        <legend>Fields</legend>
        <p>
            <label for="Username">Användarnamn: *</label>
            <%= Html.TextBox("Username", Model.User.Username) %>
            <%= Html.ValidationMessage("Username", "*") %>
        </p>
        <p>
            <label for="Firstname">Förnamn: *</label>
            <%= Html.TextBox("Firstname", Model.User.Firstname) %>
            <%= Html.ValidationMessage("Firstname", "*") %>
        </p>
        <p>
            <label for="Surname">Efternamn: *</label>
            <%= Html.TextBox("Surname", Model.User.Surname) %>
            <%= Html.ValidationMessage("Surname", "*") %>
        </p>
        <p>
            <label for="Email">E-post: *</label>
            <%= Html.TextBox("Email", Model.User.Email) %>
            <%= Html.ValidationMessage("Email", "*") %>
        </p>
        <p>
            <label for="Password">Lösenord: *</label>
            <%= Html.TextBox("Password", Model.User.Password) %>
            <%= Html.ValidationMessage("Password", "*") %>
        </p>
        <p>
            Användargrupper: <br />
            <%= Html.CheckBoxList(Model.Usergroups.Select(ug => ug.UsergroupID.ToString()), Model.Usergroups.Select(ug => ug.UsergroupName), "UsergroupID") %>
        </p>
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>

<% } %>

<div>
    <%=Html.ActionLink("Tillbaka till användare", "Users") %>
</div>

我的控制器如下：

public ActionResult UserEdit(int? userID)
    {
        User u;

        if (userID == null)
        {
            u = new User();
        }
        else
        {
            u = us.GetUsers(userID.Value).SingleOrDefault();
        }



        return View("UserEdit", new UserAdminEditViewModel { User = u, Usergroups = ug.GetUsergroups() });
    }


    [AcceptVerbs(HttpVerbs.Post)]
    //public ActionResult UserEdit([BindAttribute(Include = "Firstname,Surname,Username,Email,Password,UserID,UsergroupID")]User userobj, IList<int> UsergroupID)
    public ActionResult UserEdit(UserAdminEditViewModel userobj)
    {
        if (ModelState.IsValid)
        {
            try
            {

                //userobj.UsersUsergroups = new UsersUsergroup { UsergroupID = UsergroupID.ToList() };

                //us.SaveUser(userobj);
            }
            catch
            {
                ModelState.AddModelError("SomeError", "errrrrrrrrror");
            }
        }

        return View();
        //return View("UserDetail", new UserAdminEditViewModel { User = userobj });
    }

问题：

如果我使用我创建的UserAdminEditViewModel，则只设置IList UsergroupID的值（这是一个名为UsergroupID的复选框列表）。如果我使用User类，我可以访问所有用户属性，因为firstname等已被填写。

为什么用户对象不会在帖子上的UserAdminEditViewModel中填充？什么不见了？

编辑：

视图强烈输入“BookingSystem.MVC.ViewModels.UserAdminEditViewModel”

无法在此编辑器中显示

使用

<%= Html.TextBox("User.Firstname", Model.User.Firstname) %>

。签入渲染视图。 Formfields应呈现：

 <input  type="text" name="User.Firstname" />

绑定值不起作用
