仅在IE 10中无效的ViewState

Question

解决了: IE 10似乎在处理空字符方面有问题。因为我们正在生成大量的代码服务器端，所以缓冲导致列表项数据中的空字符，最终导致ViewState损坏(NULL不是有效的base64字符)。我注意到这一点，因为小数据集上没有发生损坏。

我已经通过在生成列表项时设置Response.Buffer = false 来解决这个问题。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，但在我的例子中，需要对存储过程进行更改()。

<option> -优雅地清除缓冲区，使NULL出现在元素之外。

在做了大量的研究之后，我仍然在我们的web应用程序中被一个无效的viewstate错误所困扰。

概括地说：

• 我使用了我在网上找到的ViewState审查员，但是它无法解析ViewState，所以没有帮助。第二对返回“不可读数据”。
• 一致的IE 10只。不会出现在任何其他浏览器中。
• 在文档模式IE9标准中工作良好(我们正在致力于支持IE10标准)
• 页面上的两个主要字段(两个列表框)将不能与EnableViewState="False"一起工作，因此解决这一问题的方法并不是理想的选项。
• 在检查了页面的源代码之后，我在Base64字符串中看到了一个Base64字符。

我的猜测是，ViewState在NUL字符处被截断，错误被抛出，因为预期的ViewState与接收的不一样。然而，我仍然停留在如何验证这一点，缩小导致数据损坏的原因，以及如何解决这个问题。

更新:我在数据集中找到了一个NUL字符，从ViewState中删除这个字符可以解决这个问题。从数据库看，数据看上去完全没有问题。假设[NUL]是一个合法的空字符

观点国家：

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

列表框中的一个选项：

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

现在我想我需要找出腐败在哪里发生的？
