ASP.NET Server Controls

Web Server Controls and Html Server Controls both derive from System.Web.UI.Control.

What is th开发者_Python百科e emphasis of the concept "server" here? Why "server" control?

ASP.NET is a server technology. These controls run on the web server, not on the client, in the browser.

They are "Server" controls because they are a server-side abstraction. They are used as controls on the server in your ASPX pages and may be directly manipulated in server-side code. However, in request processing they are translated and emitted into the response as standard HTML and (possibly) JavaScript. Thus, they are an abstraction that really only exists server side.
