两个ValidationSummaries的错误得到更新（在局部视图内）

Question

在我的小应用程序中，我有一个强类型的局部视图（登录表单），它在Masterpage中呈现，如下所示：

          <!-- Login Box -->
          <div class="login">
            <div class="login-bg clearingfix">
              <% Html.RenderPartial("LoginViewControl", Model); %>
            </div>
          </div>
          <!-- / Login Box -->

这个局部视图的模型是：

using System;
using System.Web;
using System.ComponentModel.DataAnnotations;

using mpws.Util.Validation;

    namespace mpws.Models
    {
        public class LoginViewModel
        {
            [Required]
            public string UserName { get; set; }

            [Required]
            public string Password { get; set; }

        }
    }

View本身包含Validationsummary：<%= Html.ValidationSummary() %>

我创建了另一个名为SignUp的View，它也是强类型的，类型如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;

using mpws.Util.Validation;

namespace mpws.Models
{
    public class SignUpViewModel
    {
        [Required]
        public string UserName { get; set; }

        [Required]
        public string Password { get; set; }

        [Required]
        public string FirstName { get; set; }

        [Required]
        public string LastName { get; set; }

        [Required]
        public string EmailAddress { get; set; }

        [Required]
        public string EmailAddressRepeat { get; set; }

        public string Occupation { get; set; }

        public string SuggestedBy { get; set; }

        public IValidationState validationState { get; set; }

    }
}

这里是我的SignUp View：

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<mpws.Models.SignUpViewModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    SignUp
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>SignUp</h2>

<div id="SignUpForm">
    <% using (Html.BeginForm("SignUp","Account", new mpws.Models.SignUpViewModel())) {%>
        <%: Html.ValidationSummary() %>

        <fieldset>
            <legend>Fields</legend>

            <div class="editor-label">
                <%: Html.Resource("Strings, Username") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.UserName) %>
                <%: Html.ValidationMessageFor(model => model.UserName) %>
            </div>

            <div class="editor-label">

            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.Password) %>
                <%: Html.ValidationMessageFor(model => model.Password) %>
            </div>

            <div class="editor-label">
                <%: Html.Resource("Strings, FirstName") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.FirstName) %>
                <%: Html.ValidationMessageFor(model => model.FirstName) %>
            </div>

            <div class="editor-label">
                <%: Html.Resource("Strings, LastName") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.LastName) %>
                <%: Html.ValidationMessageFor(model => model.LastName) %>
            </div>

            <div class="editor-label">
                <%: Html.Resource("Strings, EmailAddress") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.EmailAddress) %>
                <%: Html.ValidationMessageFor(model => model.EmailAddress) %>
            </div>

            <div class="editor-label">
                <%: Html.Resource("RepeatEmailAddress") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.EmailAddressRepeat) %>
                <%: Html.ValidationMessageFor(model => model.EmailAddressRepeat) %>
            </div>

            <div class="editor-label">
                <%: Html.LabelFor(model => model.Occupation) %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.Occupation) %>
                <%: Html.ValidationMessageFor(model => model.Occupation) %>
            </div>

            <div class="editor-label">
                <%: Html.LabelFor(model => model.SuggestedBy) %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.SuggestedBy) %>
                <%: Html.ValidationMessageFor(model => model.SuggestedBy) %>
            </div>

            <p>
                <button class="button positive" type="submit"> 
                      <img alt="" src="<%= ResolveUrl("~/Content/public/ui/button/tick.png") %>" /> 
                      <%: Html.Resource("Strings, SignUp") %>   
                </button>
                <button class="button negative" type="reset"> 
                      <img alt="" src="<%= ResolveUrl("~/Content/public/ui/button/cross.png") %>" /> 
                      <%: Html.Resource("Strings, Cancel") %>  
                </button>
            </p>
        </fieldset>

    <% } %>    
</div>

</asp:Content>

和登录部分查看：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<mpws.Models.LoginViewModel>" %>

<!-- This should be outsourced into it own .js fila -->
<script type="text/javascript">
    /// <reference path="jquery-1.4.1-vsdoc.js" />

    $(document).ready(function () {
        $('#LoginForm form').live('submit', function () {
            $.post($(this).attr('action'), $(this).serialize(), function (result) {
                if ($.isString(result)) {
                    $("#LoginForm").replaceWith($(result));
                }
                else if (result["Successfull"]) {
                    window.location.href = result["RedirectUrl"];
                }
                else {
                    alert('Unknown Error...');
                }
            });
            return false;
        });
    });

    jQuery.isString = function (o) {
        return (typeof o === "string");
    }
</script>

<div id="LoginForm">
    <% using (Html.BeginForm("SignIn", "Account"))
       {%>

        <fieldset>
            <legend>Login</legend>
            <%if(!ViewContext.ViewData.ModelState.IsValid) {%>
                <%= Html.ValidationSummary_jQueyUIfriendly() %>

                <%= Html.ValidationSummary() %>
                <br />  
            <%} %>

            <div class="editor-label">
                <%: Html.Resource("Strings, Username") %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.UserName)%> <br />
                <%: Html.ValidationMessageFor(model => model.UserName)%>
            </div>

            <div class="editor-label">
                <%: Html.Resource("Strings, Password") %>
            </div>
            <div class="editor-field">
                <%: Html.PasswordFor(model => model.Password)%><br />
                <%: Html.ValidationMessageFor(model => model.Password)%>
            </div>
            <p>
                <button class="button positive" type="submit"> 
                      <img alt="" src="<%= ResolveUrl("~/Content/public/ui/button/tick.png") %>" /> 
                      <%: Html.Resource("Strings, SignIn") %>
                 </button>
            </p>
        </fieldset>

    <% } %>
</div>

如果现在有人点击“SignUp” - 子按钮，验证错误会显示在signUp视图的validationsummary中，但也会显示在部分视图“LoginViewControl”的validationsummary中......任何想法为什么？我想也许Modelstate可能是全球性的handeld但是如果我点击“login”-Submitbutton，验证消息只显示在局部视图中...

有什么想法吗？
