Answer 1

You need to use datagridview for this purpose. It is designed for this purpose. You can assign the datasource to gridview and allow user to edit rows. Then by handling row edited event or by giving the button you can update the database. See an example here

Answer 2

Do you use WPF or WinForms? Anyway you need to investigate Bindings : BindingSource in WinForms or Binding class in WPF ( http://msdn.microsoft.com/en-us/library/ms750612.aspx ).

Answer 3

Look at DataTable events http://msdn.microsoft.com/en-us/library/system.data.datatable_events.aspx . There is RowChangedEvent. Call update sql command in its handler.
