当我通过NuGet将AjaxControlToolkit.dll升级到最新版本的工具包时,我的项目现在会产生一个错误,告诉我页面上有多个带有ID _header的控件。我不确定在客户端实际生成了什么,其id为_header,但我想我会先回复stackoverflow社区,然后再回滚并查看最后一个已知工作版代码的内容。
以下是错误的确切堆栈跟踪:

答案 0 :(得分:2)
这就是答案的结果:当将ASP .NET Ajax版本更新到最新版本时,现在需要为Accordion Control中的每个Accordion Pane设置一个ID。如果您没有为它们分配ID,它会为您生成一个“_header”。在我的情况下,我有超过1个手风琴窗格,所以确实有超过1个相同的ID。我希望这有助于其他人。 Here是帮助我指明正确方向的帖子。 Big Ups CurtWRC:)
