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. "

more simple solution in Master page <%: Page.Title %> - the main title goes here
in content page first line of it <%@ Page Title="Your Title" Language="C#" MasterPageFile="~/_masterpages/... etc

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.

The problem is that the Page_Load method in the page runs before the Page_Load method in the user controls in the page, and a master page is actually a user control.
You can use the Page_Init method in the master page instead.

You have to remember that the MasterPage is a child control of the Page, so the OnLoad event fires after the Page's OnLoad event.
In your scenario/example, the page would set the title, then the masterpage would set it again afterwards. Either set it later in the lifecycle or wrap some more logic around who sets it perhaps?
Scott Allen has a good article on this for Master Page's specifically, give it a quick read to get a feel for the lifecycle order.
