Hi Bhupesh,

Do you want this?

public static void GetAllChildObjectOfTypeInVisualTree<T>(DependencyObject dpob, List<T> outList) where T : DependencyObject
        int count = VisualTreeHelper.GetChildrenCount(dpob);
        for (int i = 0; i < count; i++)
            DependencyObject child = VisualTreeHelper.GetChild(dpob, i);
            T childAsT = child as T;
            if (childAsT != null)
            GetAllChildObjectOfTypeInVisualTree<T>(child, outList);


Best Regards,
