Listview display how to?

I get a string value return from the server and want to display it on a list view, but when i use the code below, I get the vertical display, not the horizontal display as I expected.
It show:
QueueParamsEvent | QueueMemberEvent | QueueEntryEvent  | .....  
Queue: Q1                 | Queue: Q1                  | Queue: Q1             | .....  
ServiceLevel: SL1    |ServiceLevel: SL2      |ServiceLevel: SL3 | .....

But I want to display it like this.
QueueParamsEvent
Queue: Q1
ServiceLevel: SL1    

QueueMemberEvent
Queue: Q2
ServiceLevel: SL2

QueueEntryEvent
Queue: Q3
ServiceLevel: SL3

Please help me correct this error:

foreach (ManagerEvent e in re.Events)
            {
                if (e is QueueParamsEvent)
                {
                    QueueParamsEvent qe = (QueueParamsEvent)e;
                    lvQueues.Items.Add("QueueParamsEvent" + "\n\tQueue:\t\t" + qe.Queue + "\n\tServiceLevel:\t" + qe.ServiceLevel);
                }
                else if (e is QueueMemberEvent)
                {
                    QueueMemberEvent qme = (QueueMemberEvent)e;
                    lvQueues.Items.Add("QueueMemberEvent" + "\n\tQueue:\t\t" + qme.Queue + "\n\tLocation:\t" + qme.Location);
                }
                else if (e is QueueEntryEvent)
                {
                    QueueEntryEvent qee = (QueueEntryEvent)e;
                    lvQueues.Items.Add("QueueEntryEvent" + "\n\tQueue:\t\t" + qee.Queue + "\n\tChannel:\t" + qee.Channel + "\n\tPosition:\t" + qee.Position);
