hihi...
anyone of you know how to create a auto generate data which can recycle the data after 30 days , i already have a primary key and it is identity specification. Bascially i am doing a web service and gridview consume the data and i need this auto generate data when i new a record in the detail view and refesh it back to the gridview, but the problem is i don't know how to create this auto generate data which i can recycle using it after 30 days( the data is something like a id) and combine with the detail view( or the insert method)
thanks in advance
