Question

我具有 DropDownList

的编辑器模板

@model object
<div class='form-fields @ViewData["class"]'>
@Html.LabelFor(x => x, new { @class = "form-fields__label" })
@Html.DropDownListFor(x => x, (SelectList)ViewData["selectList"], new { @class = "form-fields__input width-max d-block " + @ViewData["inputClass"]})
@Html.ValidationMessageFor(x => x, "", new { @class = "form-fields__form-error" })

我正在使用ViewData从View读取List数据，但是我收到错误消息，System.String没有属性'P'（这是我的状态）。我认为发生这种情况是因为当数据进入我的模板时，他只读取值，而不读取属性。有什么解决方法吗？

查看

@Html.EditorFor(x => x.AdminForEdit.Status.Status, "DropDownList", new { selectList = new SelectList(MDC.Models.Accounts.UserStatus.GetStatuses(), Model.AdminForEdit.Status.Status, NinjectWebCommon.Dictionary.GetLocalization(Model.Device.Language.LanguageId, Model.AdminForEdit.Status.Name), Model.AdminForEdit.Status.Status)})

UserStatus 类

public class UserStatus
{
    public string Status { get; set; }
    public string Name { get; set; }
    public bool AlowLogIn { get; set; }
    public string ErrorMessage { get; set; }

    public UserStatus()
    {

    }

    public UserStatus(string status, string name, bool alowLogin, string errorMessage)
    {
        Status = status;
        Name = name;
        AlowLogIn = alowLogin;
        ErrorMessage = errorMessage;
    }

    public static UserStatus Pending = new UserStatus("P", "L_USERSTATUS_PENDING", false, "L_ADMIN_LOGIN_ERRORUSERPENDING");

    public static UserStatus Active = new UserStatus("A", "L_USERSTATUS_ACTIVE", true, "L_ADMIN_LOGIN_WRONGCREDENTIALS");

    public static UserStatus Blocked = new UserStatus("B", "L_USERSTATUS_BLOCKED", false, "L_ADMIN_LOGIN_ERRORUSERBLOCKED");

    public static UserStatus Deleted = new UserStatus("D", "L_USERSTATUS_DELETED", false, "L_ADMIN_LOGIN_ERRORUSERBLOCKED");

    public static UserStatus Unknown = new UserStatus("X", "L_USERSTATUS_UNKNOWN", false, "L_ADMIN_LOGIN_ERRORUSERBLOCKED");

    public static List<UserStatus> GetStatuses()
    {
        return new List<UserStatus> { Pending, Active, Blocked, Deleted };
    }

    public static UserStatus GetStatus(string status)
    {
        switch (status)
        {
            case "P":
                return Pending;
            case "A":
                return Active;
            case "B":
                return Blocked;
            case "D":
                return Deleted;
            default:
                return Unknown;
        }
    }
}

因此，正如@vikscool所述，我通过在模板中使用(IEnumerable<SelectListItem>)ViewData["selectList"]来解决此问题，鉴于此，我选择的是这样的项目：

@Html.EditorFor(x => x.AdminForEdit.Status.Status, "DropDownList", new { selectList = MDC.Models.Accounts.UserStatus.GetStatuses().Select(x => new SelectListItem()
                           {
                                Text = NinjectWebCommon.Dictionary.GetLocalization(Model.Device.Language.LanguageId, x.Name),
                                Value = x.Status
                           }) })

DropDownList的编辑器模板，无法将View的属性绑定到模板
