The following code snippet from the complete code sample iterates on a collection of IMessengerGroup objects. Each individual group is passed into the createGroupListItem(IMessengerGroup) and a ListViewGroup item is returned. The new ListViewGroup, groupItem is added to the Items collection of the ListView, contactListView.
contactGroups = (IMessengerGroups)communicator.MyGroups;
if (contactGroups != null)
{
foreach (IMessengerGroup contactGroupItem in contactGroups)
{
ListViewGroup newGroup = createGroupListItem(contactGroupItem);
contactListView.Groups.Add(newGroup);
ListViewItem groupItem = new ListViewItem(newGroup);
contactListView.Items.Add(groupItem);
}
}
