Here is Microsoft Migrating Pairs in the Series Master pages Introduction:
Master pages are a new feature introduced in ASP. NET 2.0 to help you reduce development time for Web applications by creating a single place to maintain a consistent look and feel in a site. master pages allow you to create a template that can be used to generate a common layout for different pages in the application. the primary goal of master pages is to avoid creating each page from scratch and having to repeat the layout code. another benefit of using master pages is that if you want to change the layout of the pages in the application, you only have to update the master page, rather than each individual page.
Master pages Yes ASP. Network 2.0 By creating a page to control consistent Styles, you can shorten development Web Application time. Master pages You can create a template to generate a page in the Program (if the style is consistent) with the same layout. Master pages The main purpose is to avoid the code that controls the page style from a page that has been built, and then repeat their page creation methods. Use Master pages Another benefit is that if you want to change the Page Style in the program, you only need to change this Master page You don't have to modify it one by one.
A master page looks like any ordinary ASP. NET web page extension t for the extension (. Master instead of. aspx) and some special controls and header fields. master pages must contain one or more<Asp: contentplaceholder>Controls. These controls represent areas of replaceable content. Basically, anything that is not inContentplaceholderWill appear on any page that uses the master page.

Here, Master pages Possible and Frame They are actually different, MS In this way, their differences are:
Although master pages and frames serve a similar purpose, master pages offer much more functionality. Unlike frames, using master pages allow you:
· Bookmark a page and recall all the information on the specific page, not just the default frame page. A master page isn' t really a frame. it's a single page that contains collated content from the master page and the content page that builds on the master. therefore it looks and acts like a single web page rather than a frame.
· Work in controls and tags rather than HTML. thanks to Visual Studio, you don't have to worry about opening and closing the frame tags or modifying countless HTML attributes to ensure that each frame displays in the fashion you want. you can simply create the place holder and modify its properties through Visual Studio.
· Leverage Visual Studio's code creation to exactly ally design the layout, manage the frames, and provide all of the plumbing to link the content pages into the master page. you can add new content without having to worry that the overall HTML layout of the page will be affected.
