Question

我尝试将EnableViewStateMac设置为false，但有时aspx页面仍然会收到Invalid ViewState错误。在这种情况下，修改machine.config是不可能的。不知道该怎么办。请帮忙！

这是ASPX代码：

<%@ Page Language="C#" MasterPageFile="~/CommonPage.Master" Codebehind="Register.aspx.cs" EnableViewStateMac="false"
    Inherits="xxxxxxxx.Register" Title="Create a new Account" %>

<%@ Register TagPrefix="usc" Namespace="xxxxxx" Assembly="xxxxxxxx" %>
<%@ Register Assembly="RadComboBox.Net2" Namespace="Telerik.WebControls" TagPrefix="rad" %>
<asp:Content ID="c" ContentPlaceHolderID="content" runat="Server">
<div class="t_padleft">
    <div class="t_failure" runat="server" visible="False" id="divFailure"></div>
    <div class="t_success" runat="server" visible="False" id="divSuccess"></div>
    <asp:PlaceHolder ID="phRegister" runat="server">
    <h2 class="top">
        Login Information</h2>
    <table class="form">
        <tr>

        </tr>
        <tr>

如果您发布示例代码，也许它会对我们有帮助，例如：您在哪里设置EnableViewStateMac。

但是现在，看起来，你的字段没有正确启动，所以它的值为“null”而不是true / false。但这只是一个猜测，现在推荐更多是不可能的。 ;）

我之前遇到了无效的viewstate错误，在研究中，我认为我发生的问题出现在我的一个非常大的页面中。我读到某个地方，真正的大页面可能会发生这个问题，原因我现在忘了...

ASP.NET页面中的VIewState无效
