Hi Sasha,
What You Need ?
The Master Pages feature is available only in ASP.NET 2.0, which ships with
Visual Studio.NET Whidbey, Alpha Edition or later.
ASP.NET 2.0 introduces a new concept known as Master Pages, in which you
create a common base master file that provides a consistent layout for
multiple pages in your application. To create a Master Page, you identify
common appearance and behavior factors for the pages in your application,
and move those to a master page. In the master page, you add placeholders
called ContentPlaceHolders where the content (child) pages will insert their
custom content. When users request the content pages, ASP.NET merges the
output of the content pages with the output of the master page, resulting in
a page that combines the master page layout with the output of the content
page.
