HTML Controls

HTML controls represent common HTML elements and are available through the HTML tab of the Visual Studio .NET toolbox. You can drag these controls to a Web form and set their properties in the Properties window. An HTML control, such as Text Field or Label, is converted to its appropriate HTML equivalent, such as the <INPUT> and <DIV> element, respectively, in the source code of the ASPX file. All the HTML controls are automatically placed inside an HTML <FORM> element.

HTML controls are only of little use in ASP.NET programs because they can't be accessed from the server-side code. ASP.NET provides two other sets of controls that are much better suited for server-side programming: HTML server controls and Web server controls.
