Assembly: System.Web (in system.web.dll)
A HtmlTextWriter that represents the output stream to render HTML content on the client.
Override the RenderContents 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 RenderContents method or call the RenderChildren at the point where you want the child controls to be rendered to the text writer.
