This video looks into how Code Behind is used by ASP.NET to allow developers to handle events, such as button clicks, that are invoked by a user. The events cause post backs, which means that the content of the Web Form are sent back to the web page on the web server, and the appropriate action is taken that is coded by the developer for that event. Also, When these events are invoked, the present condition and selections of the page are preserved through View State, a hash of information that is saved into hidden form fields on the web browser client.
