3.4 Summary

• HTML server controls are HTML elements containing attributes that make them visible
to and programmable on the server.
• PostBack is the name given to the process of submitting an ASP.NET page to the server for
processing. Post Back is done if certain credentials of the page are to be checked against
a database.
• ASP.NET pages are made of code, mark-up tags, literal text, and server controls. Based
on the request, the server controls generate the right mark-up language. The ASP.NET
runtime combines the output of all controls and serves the client a page to display in a
browser.
• A naming container is primarily a control that acts as a container for other controls. In
doing so, the naming container generates a sort of virtual namespace so that ASP.NET
roots the actual ID of contained controls in the ID of the naming container.
• Control state is a collection of critical view state data that controls need to function. Because
of its critical role, control state data is contained in separate member variables from normal
view state and is not affected when view state is disabled.
