ASP.NET 2.0: Simplified Code Behind Model
ASP.NET 2.0 introduces an improved runtime for code-behind pages that simplifies the connections between the page and code. In this new code-behind model, the page is declared as a partial class, which enables both the page and code files to be compiled into a single class at runtime. The page code refers to the code-behind file in the CodeFile attribute of the directive, specifying the class name in the Inherits attribute. Note that members of the code behind class must be either public or protected (they cannot be private).
