How can I access the ListViewItems of a WPF ListView?

Question

Within an event, I\'d like to put the focus on a specific TextBox within the ListViewItem\'s template. The XAML looks like this:

I noticed that the question title does not directly relate to the content of the question, and neither does the accepted answer answer it. I have been able to "access the ListViewItems of a WPF ListView" by using this:

public static IEnumerable GetListViewItemsFromList(ListView lv)
{
    return FindChildrenOfType(lv);
}

public static IEnumerable FindChildrenOfType(this DependencyObject ob)
    where T : class
{
    foreach (var child in GetChildren(ob))
    {
        T castedChild = child as T;
        if (castedChild != null)
        {
            yield return castedChild;
        }
        else
        {
            foreach (var internalChild in FindChildrenOfType(child))
            {
                yield return internalChild;
            }
        }
    }
}

public static IEnumerable GetChildren(this DependencyObject ob)
{
    int childCount = VisualTreeHelper.GetChildrenCount(ob);

    for (int i = 0; i < childCount; i++)
    {
        yield return VisualTreeHelper.GetChild(ob, i);
    }
}

I'm not sure how hectic the recursion gets, but it seemed to work fine in my case. And no, I have not used yield return in a recursive context before.
