ASP.net writing code behind variable to HTML page code

Hey all i am trying to get this:

<div id="subpg_main">    
<%= theHeadering %>
</div>
<!-- END BODY PAGE ------------------------->

To work within my HTML code.

The code behind just has this:

Public Class thankyou
    Inherits System.Web.UI.Page
    Public theHeadering As String = ""

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim theName As String = "Bob Barker"
        Dim theEmail As String = "[email protected]"

        If theForm = "contact" Then
            theHeadering = "<H1>Thank you " & theName & " for contacting us!</H1><BR />"
            theHeadering += "We will be contacting you via your email address at " & theEmail & " within 24 hours."
        End If
    End Sub    
End Class

However, when i run the page i get the following error:

Compiler Error Message: BC30451: 'theHeadering' is not declared. It may be inaccessible due to its protection level.

It should be

 Public Property theHeadering As String = ""

And not:

 Public theHeadering As String = ""

open the designer page page.aspx.designer.vb

and add:

Protected theHeadering As String

you will now have everything working.

This is done automatically, but sometimes, the automatic part can fail.

Here is an example creating an empty WebForms project. Full image here.

Try with this

EDIT

HTML CODE

<div id="subpg_main">    
<%# TheHeadering()%>
</div>
<!-- END BODY PAGE ------------------------->


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim theName As String = "Bob Barker"
    Dim theEmail As String = "[email protected]"

    If theForm = "contact" Then
        theHeadering = "<H1>Thank you " & theName & " for contacting us!</H1><BR />"
        theHeadering += "We will be contacting you via your email address at " & theEmail & " within 24 hours."
    End If
   'Bind your expression with the markup code
   Me.DataBind()
End Sub

Add a function and call it from the HTML

<div id="subpg_main">    
<%= TheHeadering()%>
</div>
<!-- END BODY PAGE ------------------------->



Public Class thankyou
    Inherits System.Web.UI.Page
    Private headering As String = ""

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim theName As String = "Bob Barker"
        Dim theEmail As String = "[email protected]"

        If theForm = "contact" Then
            headering = "<H1>Thank you " & theName & " for contacting us!</H1><BR />"
            headering += "We will be contacting you via your email address at " & theEmail & " within 24 hours."
        End If
    End Sub    
    Public Function TheHeadering() As String
        Return headering
    End Function
End Class

My best guess is that the Page Directive of the Mark up code is pointing to another class which the have the same property theHeadering As String = "" but its not a Public access level.
