How to set Page's Title from a web content page in ASP.NET 3.5

I've read through quite a bit of posts/articles on how to do this and I still am not getting the page title set from the content page. My pages render OK except I can't get the title set from the content page (all the page's have Title set as per the master page). Here's the codebehind for my master page:

Partial Class zSEO
Inherits System.Web.UI.MasterPage
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Page.Header.Title = "Dynamically set in Master page"
    End Sub
End Class

Here is the rest of the master page:

<%@ Master Language="VB" 
EnableTheming="true"
Inherits="zSEO" 
CodeFile="zSEO.master.vb" %>
<!DOCTYPE html 
 PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
 <html xmlns="http://www.w3.org/1999/xhtml" >
     <head id="Head1" runat="server">
         <title></title>
     </head>
 <body>
 <form id="form1" runat="server">    

 <div id="container">
     <div id="content">
         <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
         </asp:contentplaceholder>
     </div>    
 </div>      
 </form>
 </body>
</html>

Yet, it is in the web content page that I want to establish the value of the for the page and I have placed this in my testing content page:

Public Partial Class zShowAd
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
    Page.Header.Title = "Dynamically set TITLE value in the content(child) page"
End Sub

End Class

Strangely, I cannot get the debugger to stop on the line above in the content page - only on the corresponding line in the master page. Clearly, I am confused on this.

I've read there are other ways to do this but this seemed to be possible from what I read at Scott Mitchell's tutorial at: Dynamically setting the Page Title in ASP.NET. Specifically, I tried to follow this from the article: "Furthermore, if you are using master pages, this code can work, as written, from either the master page or the ASP.NET page that uses the master page. In such a scenario, the region should be defined in the master page, but the ASP.NET page can still access it via Page.Header. "

So what needs to happen is this

MasterPage.Master

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
    Me.Page.Title = "Dynamically set in Master page"
End Sub

Default.aspx

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Me.Page.Title = "Dynamically set in ASPX page"
End Sub

This way your master page title is set BEFORE your content page title. If you do not set a title from the content page, the masterpage will be the default title. If you do set a title from the content page, then it will override it.
