Code Behind

[lenniekuah]

Hi Good Guys,
Please help me. I need your help.

In my office I am the only Web Developer. There are no other Web Developer.

I was confused by my co-worker programmers regarding the meaning of Code Behind. They told me there is no such Code Behind.

Please highlight which is CodeBehind from these 2 sets of sample coding:

these are from HTML

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
    <link href="MainStyleSheet.css" rel="stylesheet" type="text/css" />
</head>

-------------------------
There are from ASP.NET Form

Option Explicit On
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls

Partial Public Class MasterPage
    Inherits System.Web.UI.MasterPage

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Request.IsAuthenticated = False Then
            lblWelcome.visible = False
        Else
            lblWelcome.visible = True
        End If
    End Sub

End Class

Of the 2 sets of sample cpding which one is called CodeBehind ?

Hi Lennie,

the second one is called the Code Behind. It is usually saved in a separate file with a .vb extension. So if the first codepart is called Default.aspx then the second part is called Default.aspx.vb .

In Visual Studio, you can separate these pages in the Solution Explorer (see attachment). Check the second icon (called Show All Files).
