private T FindFirstElementInVisualTree<T>(DependencyObject parentElement) where T : DependencyObject { var count = VisualTreeHelper.GetChildrenCount(parentElement); if (count == 0) return null; for (int i = 0; i < count; i++) { var child = VisualTreeHelper.GetChild(parentElement, i); if (child != null && child is T) { return (T)child; } else { var result = FindFirstElementInVisualTree<T>(child); if (result != null) return result; } } return null; }
