Hi Sun, In order to give some special effects or look and feel to existing .Net menus may require considerable amount of time and effors (coding).Therefore, it would be better if you to try any of the third party .Net visual developement tools. You may try ComponentOne Studio Enterprise for .Net. It is a complete package for all layes of Windows (WinFormApp, WebApp, and Mobile). For more details or to download the free trial of the package please visit. www.componentone.com I hope this helps :).
