Best ASP.NET coding practices

1. Use Master Pages.
Why?
For keeping UI consistency in earlier version different User controls were created and included in different pages. A master page is a template for other pages, with shared layout and functionality. The master page defines placeholders for content pages. The result page is a combination (merge) of the master page and the content page. So for applying a consistent look and feel for a whole web site Master pages is used in .Net .

2. Use Themes and Skins.
Why?
Themes is another feature of ASP.NET . Themes, or skins, allow developers to create a customized look for web applications. Using Themes, it makes simple to customize the appearance of a site and all visual elements can be customized. Themes can be applied to controls, pages, and entire sites.

3. Use separate files for JavaScript functions and include in Master pages.
Why?
It saves repetition of same JavaScript function in different files.

4. Use SiteMaps..
