Answer 1

Using this code

public static IEnumerable FindVisualChildren(DependencyObject depObj) where T : DependencyObject
{
    if (depObj != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
            if (child != null && child is T)
            {
                yield return (T)child;
            }

            foreach (T childOfChild in FindVisualChildren(child))
            {
                yield return childOfChild;
            }
        }
    }
}

You can enumerate all controls by type.

foreach (Label lbl in FindVisualChildren(window))
{
    // do something with lbl here
}
