To ensure the user can add records but cannot delete any records, it is only necessary to remove the Delete button from the TblCustomerBindingNavigator control. This will prevent the user from accidentally or intentionally deleting any records, while still allowing them to add new records and save any changes made to existing records. Removing the Add new button or Save button is not necessary to achieve this goal.
