System.Web.UI.HtmlControls Namespace
Serves as the abstract base class that defines the methods, properties, and events common to all HTML input controls.
The HtmlInputControl class is typically not instantiated. Instead, this class provides the common basic functionality inherited by other classes, such as the HtmlInputText, HtmlInputButton, HtmlInputRadioButton, HtmlInputCheckBox, HtmlInputImage, HtmlInputHidden, and HtmlInputFile classes.
