Understanding Page Life Time:
The first time that an Asp.Net web form page is executed, the code contained with the page (any codebehind class module associated with the page ) is complied into a class that inherits from the Page base class ( actually, the code-behing class inherits from the Page class and then the .aspx file inherits from code-behind class via the Inherits attributes of the @ Page directive ).
The following illustration show the relationship between the Page, its code-behind class (if any) and the complied assembly. Once complied, the class is executed, the resulting Html is rendered to the browser, and the class removed from hte memory.
