- HtmlTextWriter
The HtmlTextWriter containing methods to render the target-specific output.
The BeginRender method is called just before the Render method, and is used to perform target-specific preprocessing before the rendering of the control.
Use the BeginRender method in combination with the EndRender method to ensure opening and closing tag consistency.
When you inherit from the ControlAdapter class, the BeginRender(HtmlTextWriter) base method calls the BeginRender() method. Thus, overrides of the BeginRender(HtmlTextWriter) method should call the BeginRender(HtmlTextWriter) base method only if its processing is in addition to, rather than instead of, the BeginRender() method.
