How Do I: Work with Nested Master Pages to Create Standard Content Layouts

In this video Chris Pels will show how to use nested master pages to create individual master pages that represent
different standard content layouts for a web site. First, see how several major commercial web sites use a standard
set of content layouts. Next, see how to nest a master page within another master page, and use the design time
support in Visual Studio 2008. Then, learn the considerations for establishing a “page architecture” which represents
the major types of content layout used in a sample web site. Once that definition is complete see how to structure
the nested master pages so developers can then select a master page, resulting in a standardized and consistent
display of content for a web site.
