Hello.
Code behind is a method for separating .NET code from HTML code. In other
words: the user interface code is in one file and the functionality for
the webform is another file.
Exempel:
#User interface starts here#
<%@ Page inherits="SomeWebForm" src="SomeWebForm.vb"%>
<html>
<body>
<form runat="server">
<asp:button id="someButton" runat="server" />
</form>
</body>
</html>
#User interface stops here
##VB.NET Code
imports system
imports system.web.ui
public class SomeWebForm: inherits Page
'the functionality goes here
end class
##VB.NET code stops
There is a lot written about this topic on the web...
Best regards,
Philip

Hi Nick,
In an ASP page, you can write the business logic either within the
.aspx page or separate it and write into another document that can be
referenced from the .aspx page.
In the example provided by Phillip, the presentation page (see code
below) defines only the presentation layer. That is the objects
required to be displayed on the page. If you observe the first line of
the code (See the code for WebForm2.aspx) you will note that this file
is referencing another file called WebForm2.aspx.vb
Now, this SomeWebForm.VB contains the processing logic for the
Button_Click Event. All you need to do is compile this
WebForm2.aspx.vb into a WebForm2.dll using the VBC command. Then copy
this dll into the BIN directory of your web server or the virtual
directory. Execute the WebForm2.aspx page from the browser.
>> Example: (FileName = WebForm2.aspx)
<%@ Page Language="VB" AutoEventWireUp="False"
CodeBehind="WebForm2.aspx.vb" Inherits="WebForm2" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title> WebForm2.aspx </title>
</head>
<body>
<form id="Form1" method="Post" runat="server">
<asp:Button id="Button1" Text="Click Here" Runat="server" />
<asp:Label id="Label1" Runat="server"> Label </asp:Label>
</form>
</body>
</html>
>> ##VB.NET Code (FileName = WebForm2.aspx.vb)
Public Class WebForm2
Inherits System.Web.UI.Page
Protected WithEvents Button1 as System.Web.UI.WebControls.Button
Protected WithEvents Label1 as System.Web.UI.WebControls.Label
Private Sub Button1_Click(ByVal s as System.Object, ByVal e as
System.EventArgs) Handles Button1.Click
Label1.Text = " Button was clicked !" & system.DateTime.Now
End Sub
End Class
Hope this helps.
Cheers,
Vidya.
