Renders the contents of the control to the specified writer. This method is used primarily by control developers.
Assembly: System.Web (in System.Web.dll)
Override the method to render the contents of the control between the begin and end tags. The default implementation of this method renders any child controls.
If your control has child controls, you must either call the base method or call the RenderChildren at the point where you want the child controls to be rendered to the text writer.
