If I have this in a page, an exception is thrown with the text page_init:

<script runat="server">
    Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        Throw New System.Exception("page_init")
    End Sub

    Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim loDataEntry As DataEntryPurchase = New DataEntryPurchase(oApp)
        loDataEntry.GenerateForm()
    End Sub
</script>

So far, so good, now, if I subclass this page and move the Page_Init() code in a class instead by doing this:

1. Add Inherits="Framework.Framework.WebForm" in the page declaration.

2. Add a small class for this:

Namespace Framework

    Public Class WebForm
        Inherits System.Web.UI.Page

        Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
            Throw New System.Exception("page_init from the class")
        End Sub

    End Class

End Namespace

The exception is never thrown. Can someone explain me why in inheritance mode that the Page_Init() event is not fired but only in the page itself?
