找不到带有 ID 的 UpdatePanel

Question

我最近将一个项目更新到了 DNN 6.0.1。我从 6.0.1 安装开始，并从那里添加了我的桌面模块。从 5.6.3 迁移到 6.0.1 时，我的一些用户控件中的某些功能出现了问题。在深入探讨之前，我得承认我有点神经病。

快速概述我有一个 ascx，它包含另一个控件中的所有功能，该控件包含 asp 向导中的几个其他控件。
（如此多的嵌套控件的原因是出于许可目的隐藏功能，并且另一个模块[也获得许可]依赖于第一个子控件中的功能）

它就像这样 Parent: ViewReportRisk.ascx >>>子级：ReportRiskWizard.ascx>>第二个子： Attachments.ascx （许可 -- 隐藏功能） （主要功能）（支持功能的控件）

向导（在子控件中）位于 Telerik RadMultiPage 内部。我遇到问题的控件（第二个子控件）包含一个包裹在 asp 更新面板中的 RadUploader。

当我在向导中单击“下一步”以使用 RadUploader 查看控件时，出现此错误：

Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'dnn_ctr445_ViewReportIssue_wzAddRisk_AttachmentsAddTemp_UpdatePanel1'. If it is being updated dynamically then it must be inside another UpdatePanel.' when calling method: [nsIDOMEventListener::handleEvent]

ID 良好。我没有动态创建控件，当我删除更新面板时，控件会出现，但上传功能会丢失。

控件快速概述（缩写）：

这在 DNN 5.6.3 版本中没有发生，仅在 6.0.1 中发生（模块中的相同代码）
只是对于 S&GI 在另一个第二个子控件上放置了一个更新面板，它引发了相同的错误，所以我确信它与控件的嵌套（父子-孙子）有关，但我不确定如何补救这个问题。

非常感谢任何帮助，提前致谢。

事实证明，我的问题的答案是将 UpdatePanel 的 UpdateMode 属性设置为 Conditional
