To	Do this
Inherit from a base class	Add the Inherits keyword on the line after the class definition, specifying the name of the class to inherit.
Render output from a control	Override the Render method of the control class from which the custom control is derived. To take advantage of the rendered output of controls such as TextBox and Label, call the Render method of the base class when you are finished rendering custom output.
Handle postbacks	Implement the IPostBackDataHandler and/or IPostBackEventHandler interfaces, and implement the methods defined by the interfaces.
Maintain state in a custom control	Store state in and retrieve state from the ViewState object in your property procedures.
