error BC30456: '[Method]' is not a member of 'ASP.[CodeBehind]_aspx'

Question

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

Answer 1

gvLegs_PageIndexChanging is private but needs to be protected or public.

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

Edit: Just to be clear, you have three options in ASP.NET with VB.NET to create event handlers:

1. declaratively on aspx
2. in code with handles clause
3. with AddHandler (mostly for dynamical controls in VB.NET)

If you use option 1 the event handler must at least be protected since the aspx page inherits from the codebehind class.

If you use option 2 the method can be private but you need to remove the declarative event handler on the aspx.
