2.3 Introduction to In-line Script
The ASP.Net web pages sustain both kinds of coding models: code-behind as well as in
sequence code. The difference between them is the in sequence code model enables to write the
code statements in the .aspx page beside with HTML source code using <script> tag whereas
code-behind model separate the .aspx page and server-side code. You can write the code in
a disconnect .cs or .vb code file derived from Page class especially for each .aspx page. The
other very important difference is that the inline code is deployed along with the .aspx web
page when a compiled web application is published online whereas the code-behind approach
compiles the code for all web pages into a .dll file that enables to host the web pages free from
any inline server code.
Using this syntax, you can use in sequence code in ASP.NET (.aspx) pages. The server-side
code will be mechanically compiled by the .NET framework the first point in time the page
is requested on the server. The compiled .dll file is stored in the “Temporary ASP.NET Files”
system folder. Changing the code in .aspx files will trigger a new compilation, generating new
.dll files. The old .dll files are phased out by the framework and eventually deleted.
