ASP.NET MVC Html.ValidationSummary（真）不显示模型误差 [英] ASP.NET MVC Html.ValidationSummary(true) does not display model errors

问题描述

我有一些问题，Html.ValidationSummary。我不想的ValidationSummary显示属性的错误。而当我设Html.ValidationSummary（真）不显示从ModelState中的错误信息。当有一些异常的控制器行动字符串

  MembersManager.RegisterMember（会员）;
 

捕节将错误的ModelState中：

  ModelState.AddModelError（错误，ex.Message）;
 

不过的ValidationSummary不显示此错误消息。当我设置Html.ValidationSummary（假）的所有消息都显示，但我不希望显示属性的错误。我怎样才能解决这个问题？

下面是code我使用的是：

型号：

 公共类会员
{
        [必需（的ErrorMessage =*）]
        [显示名称（登录）]
        公共字符串登录{搞定;组; }        [必需（的ErrorMessage =*）]
        [数据类型（DataType.Password）
        [显示名称（密码）]
        公共字符串密码{搞定;组; }        [必需（的ErrorMessage =*）]
        [数据类型（DataType.Password）
        [显示名称（确认密码）]
        公共字符串ConfirmPassword {搞定;组; }
}
 

控制器：

  [HttpPost]
公众的ActionResult注册（注​​册会员）
{
    尝试
    {
        如果（！ModelState.IsValid）
            返回查看（）;        MembersManager.RegisterMember（会员）;
    }
    赶上（异常前）
    {
        ModelState.AddModelError（错误，ex.Message）;        返回查看（会员）;
    }
}
 

查看：

 ＆LT;使用（Html.BeginForm（注册，成员％FormMethod.Post，
                        新{ENCTYPE =的multipart / form-data的}））{％GT;
    ＆所述p为H.;

解决方案

我相信在ValidationSummary标志的工作方式是将只显示为ModelErrors 的String.Empty 作为键。否则，假设它是一个属性错误。没有验证您提供的字符串/未在模型的属性。

  ModelState.AddModelError（的String.Empty，ex.Message）;
 

I have some problem with Html.ValidationSummary. I don't want to display property errors in ValidationSummary. And when I set Html.ValidationSummary(true) it does not display error messages from ModelState. When there is some Exception in controller action on string

MembersManager.RegisterMember(member);

catch section adds an error to the ModelState:

ModelState.AddModelError("error", ex.Message);

But ValidationSummary does not display this error message. When I set Html.ValidationSummary(false) all messages are displaying, but I don't want to display property errors. How can I fix this problem?

Here is the code I'm using:

Model:

public class Member
{
        [Required(ErrorMessage = "*")]
        [DisplayName("Login:")]
        public string Login { get; set; }

        [Required(ErrorMessage = "*")]
        [DataType(DataType.Password)]
        [DisplayName("Password:")]
        public string Password { get; set; }

        [Required(ErrorMessage = "*")]
        [DataType(DataType.Password)]
        [DisplayName("Confirm Password:")]
        public string ConfirmPassword { get; set; }
}

Controller:

[HttpPost]
public ActionResult Register(Member member)
{
    try
    {
        if (!ModelState.IsValid)
            return View();

        MembersManager.RegisterMember(member);
    }
    catch (Exception ex)
    {
        ModelState.AddModelError("error", ex.Message);

        return View(member);
    }
}

View:

<% using (Html.BeginForm("Register", "Members", FormMethod.Post, 
                        new { enctype = "multipart/form-data" })) {%> 
    <p>
        <%= Html.LabelFor(model => model.Login)%>
        <%= Html.TextBoxFor(model => model.Login)%>
        <%= Html.ValidationMessageFor(model => model.Login)%>
    </p>

    <p>
        <%= Html.LabelFor(model => model.Password)%>
        <%= Html.PasswordFor(model => model.Password)%>
        <%= Html.ValidationMessageFor(model => model.Password)%>
    </p>

    <p>
        <%= Html.LabelFor(model => model.ConfirmPassword)%>
        <%= Html.PasswordFor(model => model.ConfirmPassword)%>
        <%= Html.ValidationMessageFor(model => model.ConfirmPassword)%>
    </p>

    <div>
        <input type="submit" value="Create" />
    </div>

    <%= Html.ValidationSummary(true)%>
<% } %>

解决方案

I believe the way the ValidationSummary flag works is it will only display ModelErrors for string.empty as the key. Otherwise it is assumed it is a property error. There is no validation that the string you provide is/isn't a property on the Model.

ModelState.AddModelError(string.Empty, ex.Message);
