属性不适用于模型ASP.asp.net MVC 5

我在我的web应用程序中有这个模型:

    namespace BoardMeeting.Models
{
    public class ChangePassModel
    {
        [Required(ErrorMessage = "password must be entered")]
        [DataType(DataType.Password)]
        public string Password { get; set; }
        public string Username { get; set; }
        [Required(ErrorMessage = "you must enter the new password")]
        [DataType(DataType.Password)]
        public string NewPass { set; get; }
        [DataType(DataType.Password)]
        [Compare("NewPass", ErrorMessage = "The Passwords Do not match")]
        public string ConfimedPass { set; get; }
    }
}

And Here is my View:

@model BoardMeeting.Models.ChangePassModel
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@using (Html.BeginForm())
{
    <div class="form-group ">
        <div class="row" dir="rtl">
            <div>
                @Html.Label("username :", new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.LabelFor(m => m.Username, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.Label("user :", new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.LabelFor(m => m.Username, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2  pull-right", style = "margin-top:5px;" })
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="row" dir="rtl">
            <div>
                @Html.Label("old password", new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.TextBoxFor(m=>m.Password, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right form-control", style = "margin-top:5px;" })
                @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })              
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="row" dir="rtl">
            <div>
                @Html.Label("new password", new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.TextBoxFor(m => m.NewPass, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right form-control", style = "margin-top:5px;" })
                @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="row" dir="rtl" style="align-content:center">
            <div>
                @Html.Label("confirm new password", new { @class = "col-xs-12 col-md-4 col-sm-3 col-lg-2 pull-right", style = "margin-top:5px;" })
            </div>
            <div>
                @Html.TextBoxFor(m => m.ConfimedPass, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right form-control", style = "margin-top:5px;",type="password" })
                @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="submit" class="btn btn-success pull-right" />
        </div>
    </div>
}

问题是模型的所有属性都不起作用。我已勾选以下选项:我在我的网上有这个值。appsettings下的配置文件:

<add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />

2-我已经检查了ModelState。在我的控制器中是有效的。奇怪的是，我有一个类似的代码为我的登录，它没有问题。我应该说我是ASP的新手。. NET MVC和我不知道是否还有什么我应该做的。你对这个问题有什么建议吗?

属性不适用于模型ASP.asp.net MVC 5

这里有一些错误。

你正在使用一个重载，它将错误信息设置为一个空字符串。

注意下面的第二个参数。

@Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })

只需将空白字符串替换为null，它就会从属性中取出它:

@Html.ValidationMessageFor(m => m.Password, null, new { @class = "text-danger" })

您还复制并粘贴了相同的代码每个属性下面，但保留Password作为第一个参数:

@Html.TextBoxFor(m => m.NewPass, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right form-control", style = "margin-top:5px;" })
@Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })

您需要更改它们以匹配上面的控件，并替换空白字符串:

@Html.TextBoxFor(m => m.NewPass, new { @class = "col-xs-12 col-md-2 col-sm-3 col-lg-2 pull-right form-control", style = "margin-top:5px;" })
@Html.ValidationMessageFor(m => m.NewPass, null, new { @class = "text-danger" })

视图中的所有属性都需要这样做
