I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage
End Get
End Property
How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?

My computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
00000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
It just gives me a whole page full of numbers like this. I haven't backed up for a few weeks and so I hope I can get this back.

Master page:
<form runat="server">
<Scirra:MainMenu runat="server" ID="MainMenu" TopTabSelected="home" SubTabSelected="link2" />
<asp:ContentPlaceHolder id="MainContent" runat="server">
snip
Content page:
Master.MainMenu.TopTabSelected = "forum";
I know I'm probably doing this wrong, but is this possible? I want to change a parameter of that control. It says 'inaccessible due to protection level'.

I have a CSS class called selected which highlights the DIV as the current step. When they're all in separate pages, I just had to move the selected word to the next DIV.
But how can I achieve the same in Master Page VB .Net? It seems to be one page for all. When the next page loads, how do I get it to highlight the next step?
<div id="Div1">
<div class="step selected" id="Div2">
<h2>
Join</h2>
<img src="./assets/images/signup_arrow.png" class="selected">
</div>
<div class="step" id="Div3">
<h2>
Choose</h2>
</div>
<div class="step" id="Div4">
<h2>
INVITE</h2>
</div>
</div>

Using ASP.Net 4.0, MVC 2, Visual Studio 2010.
I am building a chat control, which is a div with a background image, textarea, text box and some image. The CSS for this div on the Master Page is:
[Code]....
When a user navigates to the page where they can start a chat session by clicking on an icon, I use jQuery to change the CSS, like so:
[Code]....
The CSS for showing the chat is the same as the above CSS, only .chatWindowShow does not have the display:none property.
The problem is that once I navigate to another page, the div is hidden again, the CSS does not persist accross postbacks for some reason. What I want is that once the chat window is shown, no matter what other pages the users go to it will continue to show, until they click the close icon in the chat window.
So, how can I persist this CSS page accross all pages? I thought that removing the CSS class and adding the new one via jQuery actually modificate the inline HTML, but I guess not. Do I need to use some other jQuery to accomplish this?
Here is the HTML markup for my chat window:
[Code]....
And the jQuery which toggles the view when you click on the chatRight div:
[Code]....

I am attempting to access a textbox control on a master page from a code behind base class but having problems.
I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.
m3.master has a textbox as shown below
<%Master
Language="C#"
MasterPageFile="~/m2.master"
AutoEventWireup="true"
CodeFile="M3.master.cs"
Inherits="M3"
%>
<asp:Content
ID="Content5"
ContentPlaceHolderID="M2"
Runat="Server">
<asp:TextBox
ID="text1"
runat="server"
></asp:TextBox>
<asp:ContentPlaceHolder
ID="M3"
runat="Server"></asp:ContentPlaceHolder>
</asp:Content>
I have a content page c1.aspx that uses m3.master as its master page as shown below:
<%@
Page
Title=""
Language="C#"
MasterPageFile="~/m3.master"
AutoEventWireup="true"
CodeFile="c1.aspx.cs"
Inherits="_c1"
%>
<%@
MasterType
VirtualPath="~/m3.master"
%>
<asp:Content
ID="Content1"
ContentPlaceHolderID="M3"
Runat="Server">
</asp:Content>
My content page codebehind class inherits from a base class BaseForm
public partial
class
_c :
BaseForm{}
The problem that i am having is that I cannot access the texbox from the class BaseForm. The BaseForm code is as follows:
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public...........

I need to create my first (and simple) .net 4 web application that needs to be viewed in English, French and Italian. I've created and tested a sample web application that works fine with implicit and explicit localization set via web browser language preferences.
Now I'd like to add a simple Combo Box in the master page or in the login page to let the user choose the preferred language and would like the site to change its language based on this. I do not know how to start and to accomplish this task.

I am thinking that it would be better to use multipe CSS files and change them within the master page dynamically than it would be to use multiple master pages (basically one master page for each page, which defeats the purpose of the master page).
However, I do not know how to make a change to the master page before a standard apsx page that is derived from it is loaded.
