我遇到了一个可怕的异常，无法注销ID为“UpdatePanel”的UpdatePanel，因为在尝试组合弹出窗口和一些跨页面发布时，它未向ScriptManager注册。我用一个小例子再现了这个问题

我已经看到了处理UpdatePanel卸载事件的其他问题，但是添加跨页面发布似乎不起作用

我如何回避这个问题

要使用以下代码复制问题，请执行以下操作：

启动设置页面按查看弹出链接关闭弹出窗口按“下一步”按钮以转到目标页面按“上一步”按钮转到设置页面按查看链接并关闭弹出窗口按下Next（下一步）按钮，查看故障以下是长度的亮点，但它应该是可切割的：

Setup.aspx

ViewData.aspx

TargetPage.aspx

正如您所看到的，只要将UpdatePanel放在页面上，什么也不做就足够了。无意冒犯，但您忽略了指定问题。很好的用户名，BTW@AnnL. 没有人拿。已更新并指定我不希望有此行为。
