解决：IE 10似乎在处理空字符时遇到问题。因为我们正在生成大量代码服务器端，所以缓冲导致List Item数据中出现NULL字符，最终破坏了ViewState（NULL不是有效的base64字符）。我注意到了这一点，因为小数据集上没有发生损坏
我通过在生成列表项时设置Response.Buffer = false来解决此问题。我涉足的其他可能的解决方案：
- 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
- 正常清除缓冲区，使NULL显示在<option>元素之外
经过大量的研究后，我仍然在Web应用程序中遇到无效的viewstate错误。
总结：
EnableViewState="False"，因此有关此方法的解决方法不是理想选项。NUL个字符。 我的猜测是，在NUL字符处截断了ViewState，并且抛出了错误，因为预期的ViewState与接收的内容不同。但是，我坚持如何验证这一点，缩小导致损坏数据的原因，以及如何解决问题。
[NUL]是一个合法的空字符查看状态：
...pZmUFBTE[NUL]4NjoxZxAFD1RJQUEt...
列表框中的一个选项：
<option value="201:1" title="Pr[NUL]emier 20">Premier 20</option>
