Hi

I am creating a application using VB.Net and i wan to know what is this Master page ?....When i try to add new file there is a file called masterpage.Master where is this usefull and for what can any explain!!......

Let's say every page on your site will have the same header, footer, and navigation.
You don't want to create the header, footer, and navigation for each page of your site.
Instead, you use a MasterPage which contains the header, footer, and navigation.
Than each page on your site will use the master page and add it's own "content".

On this site, every page has the same header (ie. logos and navigation at the top).
When you look at a post and reply to a post you are on different pages but the header is always the same.
This is done with a master page.

Thanks for your answer..Thanks a lot 

 Master Page:

A Master Page enables you to share the same content among multiple content pages in a website. You can use a Master Page to create a common page layout. For example, if you want all the pages in your website to share a three-column layout, you can create the layout once in a Master Page and apply the layout to multiple content pages.

You also can use Master Pages to display common content in multiple pages. For example, if you want to display a standard header and footer in each page in your website, then you can create the standard header and footer in a Master Page.

By taking advantage of Master Pages, you can make your website easier to maintain, extend, and modify. If you need to add a new page to your website that looks just like the other pages in your website, then you simply need to apply the same Master Page to the new content page. If you decide to completely modify the design of your website, you do not need to change every content page. You can modify just a single Master Page to dramatically change the appearance of all the pages in your application.

You should have contentplaceholder control in master page . In .aspx page you should have Content control so that you can call the master page you have created in .aspx page and you should set MasterPageFile property

and ContentPlaceHolderID attribute as fallows:

Ex:

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Source_LogIn_Company_Dynamic_appoin_Default" Title="OuterStuff's Appointment Details" %>
