Button 在循环ASP.Net VB中创建时不会激发动态按钮单击事件

我有同样的问题，但是我已经声明了page_Init事件中的所有控件。当我为循环中动态创建的按钮声明事件处理程序并将其地址设置为x函数时，它不起作用

有人能帮忙吗

以下是我的页面_Init中的代码：

以下是Nxt_btn_单击事件的代码：

找到解决办法了

在子循环中创建的按钮使用common button.id声明，尽管它们是在不同的UpdatePanel>面板中创建的，但分配给它们的ID相同。我所要做的就是更正这行代码

从 TempNxt_Button.ID=MyNextButton&i

到

此外，子循环现在使用x作为整数，而不是i

Private Sub DynamicControls_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
