Called prior to the rendering of a control. In a derived adapter class, generates opening tags that are required by a specific target but not needed by HTML browsers.
Assembly: System.Web (in System.Web.dll)
The method is called just before the Render method, and is used to perform target-specific preprocessing before the rendering of the control.
Use the method in combination with the EndRender method to ensure opening and closing tag consistency.Notes to Inheritors:
When you inherit from the ControlAdapter class, the base method calls the BeginRender method. Thus, overrides of the method should call the base method only if its processing is in addition to, rather than instead of, the HtmlTextWriter.BeginRender method.
