Hi There are a few differences in the processing of code - behind and single-file(Inline) pages. Code Behind Single File The HTML and controls are in the .aspx file and the code is in a separate .aspx.vb or .aspx.cs file. The code is in blocks in the same .aspx file that contains the HTML and controls. The code for the page is compiled into a separate class from which the .aspx file derives. The .aspx file derives from the Page class. All project class files (without the .aspx file itself) are compiled into a .dll file which is deployed to the server without any source code . When a request for the page is received then an instance of the project .dll file is created and executed. When the page is deployed the source code is deployed along with the Web Forms page because it is physically in the .aspx file. However you do not see the code  only the results are rendered when the page runs.

Hi The ASP.Net provides the web page can be written in two ways. 1) Inline code 2) Code behind. Inline: The inline is design and design will be mixed in the .aspx page. The events and methods can be written part of the .aspx page. The inline can be selected while creating the web page it asks the option Separate the code File. When it is unchecked it will not create the .aspx.cs file. The developer can write the code file in the script tag. When you write the code in .aspx page it does not mean the written code will be visible to the users in the client browser like javascript. Code Behind: The code behind is code will be separated from the design page. It will create the .cs or .vb file for write the properties events and methods in the class. It will be referred to the code file in the page directive. Best: The code behind file is best. because there are some reasons. 1) Logic is separated from the design so its good readability and easy to understand 2) The designers can work on the .aspx page and the developers can focus on the function in the server side. 3) It will avoid to make the confuse of javascript section and code section For more Info: http://www.codeproject.com/Articles/8178/Inline-Single-File-vs-CodeBehind
