Now what about code-behind pages? Well, they are basically exactly the same. See the sample below.

Public Class CodeBehind : Inherits HeaderTemplate Public Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) MyBase.SampleText.Text = "Hello there" End Sub End Class

This is part of the same namespace that you created before. If you run it on an ASPX page like

<%@ Inherits="AGASPTemplates.CodeBehind" Src="TemplateCode.vb" %>

Live Demo

Now, if you look at the demo, you will see that there is a problem. The page still shows - "This is a page template sample" on it. This is because of the page execution order.
