有一个问题，我很困惑为什么它不起作用。我有一个嵌套在AJAX Accordion中的ListView控件，它嵌套在另一个AJAX Accordion中。
即。 Accordion1＆lt; Accordion2＆lt;的ListView
所有这些控件都在代码隐藏中进行数据绑定。
我目前实现了一种方法，允许我编辑任何ListView的内容，但这仅适用于Accordion1的第一个窗格。只要它在Accordion1的第一个窗格中，每条记录都可以编辑而没有任何问题。
当我在ListView中单击“编辑”按钮时，它位于Accordion1的任何其他窗格中时，它不会将ListView更改为EditItemTemplate。我认为这可能是分配给ListViews的UniqueID的命名问题，但它们是不同的（虽然不是很多）。
（（System.Web.UI.Control）（lSender））。UniqueID“ctl00 $ MainContent $ ticketAccordion $ acc_ticketTypeAccordion_Pane_0_content $ acc_ticketAccord＆gt; ion_Pane_0_content $ LV_ticketDataListview”string
（（System.Web.UI.Control）（lSender））。UniqueID“ctl00 $ MainContent $ ticketAccordion $ acc_ticketTypeAccordion_Pane_1_content $ acc_ticketAccord＆gt; ion_Pane_0_content $ LV_ticketDataListview”string
以下是我的控件代码：

答案 0 :(得分：0)
找到我的问题的修复程序。经过大量的谷歌搜索，我发现问题是嵌套控件的ClientID是相同的。
