aspx inheritance woes

Date: 06/29/06 (Asp Dot Net) Keywords: asp, web

Want to see something wonderful? Fire up visual studio and start a new asp.net web application.

Make WebForm1.aspx look like this:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="WebApplication1.child"%>

And make WebForm1.aspx.vb look like this:

Public Class parent
    Inherits System.Web.UI.Page

    Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Response.Write("parent.Page_Load")
    End Sub
End Class

Public Class child
    Inherits parent

    Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Response.Write("child.Page_Load")
    End Sub
End Class

Press F5. The resulting page will only say "parent.Page_Load". If you go back and look at WebForm1.aspx, you will see that visual studio has changed "child" to "parent" for you! You can go ahead and change it back, but the next time you recompile, it will change it for you again!
