Adds HTML attributes and styles that need to be rendered to the specified System.Web.UI.HtmlTextWriter object.
The System.Web.UI.WebControls.Menu control overrides the WebControl.AddAttributesToRender(System.Web.UI.HtmlTextWriter) method to reset the WebControl.AccessKey property to string.Empty. This member is primarily used by control developers when deriving a custom control from the System.Web.UI.WebControls.Menu class.
