我认为我的部分观点是这样，我不知道为什么。

//以下是部分视图

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



<%= Html.Label("UserName","UserName") %>
<%= Html.TextBox("UserName") %>
<%= Html.ValidationMessage("UserName") %>

<br />

<%= Html.Label("Password","Password") %>
<%= Html.Password("Password")%>
<%= Html.ValidationMessage("Password")%>

<br />

<%= Html.Label("ConfirmPassword", "Confirm Password")%>
<%= Html.Password("ConfirmPassword")%>
<%= Html.ValidationMessage("ConfirmPassword")%>

<br />

<%= Html.Label("Email","Email") %>
<%= Html.TextBox("Email") %>
<%= Html.ValidationMessage("Email")%>

<br />


<%= Html.Label("ConfirmEmail","Confirm Email") %>
<%= Html.TextBox("ConfirmEmail")%>
<%= Html.ValidationMessage("ConfirmEmail")%>

<br />

// follow位于其中一个母版页内容占位符的.aspx页面中

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">

    <form id="form1" runat="server">


    <% using ())
       { %>
            <%= Html.ValidationSummary()%>

           <% Html.RenderPartial("CoreRegistration"); %>

            <%= Html.SubmitButton("CreateAccount", "Create Account")%>

    <% } %>




</form>

点击创建帐户会导致我收到错误。

Answer 1

ASP.NET MVC不支持服务器端表单（特别是，这个）：

<form id="form1" runat="server">

使用Html.BeginForm（）在MVC中打开一个新表单。

Answer 2

ViewState不是asp.net mvc的一部分。如果您使用的是依赖于ViewState的常规ASP.Net webcontrol，它们将不起作用。

我建议使用

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

而不是您当前的表单标签。

如何禁用部分视图ViewState？
