How do I list UIElements in ListView items?

Question

I'm trying to access UIElements in the VisualTree of a ListView but the ItemsCollection is empty even though the ListView IsLoaded, IsInitialized and has items in DataContext.

How can I access UIElements in a ListView? Is there an event I can attach myself on to wait for the items to be accessible?

Thanks

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

myListView.ItemContainerGenerator.StatusChanged += OnListViewItemsStatusChanged;

-

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