ViewState仅在IE 10中无效

已解决：IE 10似乎在处理null字符方面存在问题。由于我们在服务器端生成了大量代码，缓冲导致列表项数据中出现NULL字符，最终损坏了ViewState（NULL不是有效的base64字符）。我注意到这一点是因为损坏并没有发生在小型数据集上

我已通过在生成列表项时设置Response.Buffer = false解决了此问题。我尝试过的其他可能的解决方案：

-列表框数据的ListBox.DataSource = new DataView(dataTable)和ListBox.DataBind()。这导致了干净的数据，但在我的情况下需要更改存储过程

-优雅地清除缓冲区，使NULL出现在<option>元素之外

经过大量研究，我仍然在我们的web应用程序中遇到一个无效的视图状态错误。

总结：

• 我使用了我在网上找到的ViewState检查器，但它无法解析ViewState，所以没有帮助。第二对返回"Unreadable data"
• 仅在IE 10中保持一致。不显示在任何其他浏览器中
• 在文档模式IE9标准中运行良好（我们正在支持IE10标准）
• 页面上的两个主要字段（两个列表框）将不适用于EnableViewState="False"，因此不希望使用与此相关的变通方法
• 在检查了页面的源代码后，我看到Base64字符串中有一个NUL字符

我的猜测是，ViewState在NUL字符处被截断，并且抛出错误是因为预期的ViewState与接收到的不同。然而，我一直纠结于如何验证这一点，缩小导致数据损坏的原因，以及如何解决问题。

更新：我在数据集中发现了一个NUL字符，从ViewState中删除这个字符解决了这个问题。。。查看数据库，数据看起来完全不错。假设[NUL]是合法的空字符

视图状态：

...pZmUFBTE[NUL]4NjoxZxAFD1RJQUEt...

列表框中的选项之一：

<option value="201:1" title="Pr[NUL]emier 20">Premier 20</option>

现在，我想我需要追踪这种腐败发生在哪里
