Question

我目前正在使用Sharepoint运行的ASP.Net网站。在我遇到问题之前，让我给你一些背景信息..

我开发了UserControls，然后将其添加到sharepoint页面上的webparts。其中一些webparts在sharepoint页面加载时动态加载。

这就是我们这样做的方式：

创建一个应用程序页面（InfoPage），将实际用户控件加载到应用程序页面中

＆lt; form id =“frmInfoPage”runat =“server”＆gt; ＆lt; div id =“infopage”runat =“server”＆gt;＆lt; / div＆gt; ＆LT; /形式＆GT;

创建一个UserControl（InfoContainer），它使用以下代码抓取'InfoPage'并将其添加到'InfoContainer'中的div中：

        <div id="InfoContainerDiv"/>    


        <script language="javascript" type="text/javascript">
            var numRando = Math.floor(Math.random() * 101);
            $("#InfoContainerDiv").load("url of application page"<%=Query%>&rndNum=" + numRando);
        </script>

然后将此容器放入SharePoint页面......

所以问题是当sharepoint页面呈现时，会有3个__VIEWSTATE隐藏字段（2个用于动态加载的控件和SP页面），IE7-9将用逗号连接。 ie / WSteyxeetYRduiylgkdxr，TUIFbiygutifTUfuvFufVvIUCF，ITcvuVuyfIYRCTECOBPOUIBHv

当服务器尝试解码ViewState时，这会导致回发错误：

<pre lang="HTML">

我尝试了什么：

在所有控件上禁用EnableViewstate（__VIEWSTATE隐藏字段仍然存在）
删除Page_Init上的__VIEWSTATE字段（这会导致ViewStateMac错误）
将viewstate加密模式设置为'never'（没有区别）
在配置中禁用和加密以及viewstateMac。（获取SessionState错误）

有人可以给我一些意见/建议我希望我提供了足够的信息，而且，我想要理解这个问题而不仅仅是以另一种方式做到这一点......设计就像以前的sharepoint问题一样。

谢谢。

Answer 1

您可以使用LoadPageStateFromPersistenceMedium()的{{1}}函数对您的视图状态进行自定义反序列化，其中包含打破其'，'的逗号：

System.Web.UI.Page

这只是一个想法，你需要调试，并使用它来使它适用于你的问题。

Answer 2

添加回调以删除其他ViewState隐藏字段： $（“＃InfoContainerDiv”）。load（“应用程序页面的网址”＆lt;％=查询％＆gt;＆amp; rndNum =“+ numRando，function（）{删除动态加载的VIEWSTATE隐藏字段。 }）;

回发时IE中的ViewState错误
