错误BC30456：'[方法]'不是一个成员。“ASP [codeBehind] _aspx” [英] error BC30456: '[Method]' is not a member of 'ASP.[CodeBehind]_aspx'
问题描述
pretty简单的问题。我很肯定我有类，方法，codebehind等正确关联。很多帖子在网上说这事做编译和/或DLL / bin中的文件，但没有他们的帮助很适合我。
Pretty simple question. I'm quite certain I have the Class, method, codebehind, etc linked properly. Lot's of posts online say that this has something to do with compiling and/or dll/bin files, but none of their help has worked for me.
Compiler Error Message: BC30456: 'gvLegs_PageIndexChanging' is not a member of 'ASP.nestedgridview_aspx'.

Private Sub gvLegs_PageIndexChanging(sender As Object, e As GridViewPageEventArgs)
如果任何人有这个修复，这会对我们帮助很大，所以我可以继续调试....实际code笑。
If anyone has a fix for this, it would help me greatly so I can continue.... debugging the actual code lol.
推荐答案
gvLegs_PageIndexChanging 是私有的，但需要保护或公开。
gvLegs_PageIndexChanging is private but needs to be protected or public.
由于您使用VB.NET，你也可以使用处理条款：
Since you're using VB.NET you could also use the handles clause:
Private Sub gvLegs_PageIndexChanging(sender As Object, e As GridViewPageEventArgs) _
Handles gvLegs.PageIndexChanging
End Sub
修改：只要是明确的，你必须在ASP.NET三种选择用VB.NET创建事件处理程序：
Edit: Just to be clear, you have three options in ASP.NET with VB.NET to create event handlers:
- 声明上ASPX
- 在code。与处理条款
- 使用的AddHandler （大多为在VB动态控制.NET）
- declaratively on aspx
- in code with handles clause
- with AddHandler (mostly for dynamical controls in VB.NET)
如果您使用选项1事件处理程序至少必须得到保护，因为aspx页面从codebehind类继承。
If you use option 1 the event handler must at least be protected since the aspx page inherits from the codebehind class.
如果您使用选项2的方法可以是私有的，但你需要删除的ASPX声明事件处理程序。
If you use option 2 the method can be private but you need to remove the declarative event handler on the aspx.
