Yes you can delete the guest, see MSDN's explanation of a SQL Delete statement.

You need to set the parameters for your update function, see the SqlCommand.CreateParameter function.

Well, see, your stored procedure requires the guest_id as the first parameter, but you dont seem to send that thru the procedure.
Hint : you can actually have a variable named guest_id in ur appication and you can fill the varaible when u retrieve it.
during an update you can send the same variable as a parameter.

YES, Deleting through autogenerated is very much possible.
