System.Web.UI.WebControls

The System.Web.UI.WebControls namespace is a collection of classes that allow you to create Web server controls on a Web page. Web server controls run on the server and include form controls such as buttons and text boxes. They also include special purpose controls such as a calendar. Because Web server controls run on the server, you can programmatically control these elements. Web server controls are more abstract than HTML server controls. Their object model does not necessarily reflect HTML syntax.
