No, a webservice does not have a mechanism to call it's clients. You could add a webservice to your asp.net application and have your other webservice call that to notify you, if you control both sites. Otherwise, no.

i cant get it , how to notify

ASP.NET site A calls a webservice hosted on site B. The only way site B can tell site A to call the webservice, is if ASP.NET site A has a webservice which site B can call to say 'my data has updated'. You need to add code on the side that hosts the webservice you are calling, to send you a notification.
