推荐答案

你是一个幸运的人 - 我刚刚写了一篇文章，解释了控件ID如何在ASP.NET模板中运行...

了解ASP.NET模板 [ ^ ]

想想看它 - 你有几个按钮，据说有相同的ID - sot你想绑定触发器到哪个控件？

如果您阅读MSDN关于 AsyncPostBackTrigger [ ^ ] - 你可以看到你必须提供一个标识单个控件的特定ID！

可能你唯一的（也是最好的）选择是来自代码隐藏 - http://msdn.microsoft.com/ en-us / library / system.web.ui.scriptmanager.registerasyncpostbackcontrol.aspx [ ^ ]

You are a fortunate man - I just wrote an article that explains how Control ID works in ASP.NET templates...
Understanding ASP.NET Templates[^]
Think about it - you have several buttons, that supposedly have the same ID - sot to which control do you want to bind the trigger?
If you read MSDN about AsyncPostBackTrigger[^] - you can see that you have to provide a specific ID, that identifies a single control!
Probably your only (and best) option is to do it from the code-behind - http://msdn.microsoft.com/en-us/library/system.web.ui.scriptmanager.registerasyncpostbackcontrol.aspx[^]
