You can subscribe to ItemsContainerGenerator.StatusChanged, and in the handler, check whether the status has ContainersGenerated:

myListView.ItemContainerGenerator.StatusChanged += OnListViewItemsStatusChanged;

-

private void OnListViewItemsStatusChanged(object sender, EventArgs e) {
    if (myListView.ItemContainerGenerator.Status == GeneratorStatus.ContainersGenerated) {
        // access items
    }
}
