Data Binding, Navigation, and Manipulation

Question

Hi
I am a VB6 programmer now planed to swith over to C#. Well, so far the conceptual understanding of connection, adapter, dataset, datatable, datarow, and dataview is concerned I get it.
But I am still unable to do the navigational operations (movefirst, movelast, moveprevious, movenet) on a from after binding controls and I am still confuse that if I add buttons for Add, Update, and Delete operations on that form what code I will write for them to change not only dataset but actual databse too.
Thank you so very much.
