Understanding and using server controls

understanding and using server controls


An ASP.NET server control is a control that provides both user functionality and programmability through a server-side event model. For example, a Button control allows users to trigger an action, such as indicating they have completed a task. In addition, the Button control is posted back to the server where ASP.NET is able to match the control with its associated event code (an on-click event, for instance). The server controls that ship with ASP.NET allow you to write code against a well-defined object model. In fact, all server controls, including the Web page class itself, inherit from the System.Web.UI.Control class.

There are two primary types of server controls in ASP.NET: HTML and Web. The HTML controls provide server-side processing that generally maps back to an HTML input element like a text box or submit button. The Web controls are ASP.NET controls that focus more on their object model and less on their HTML rendering aspects.
