Auto scroll the Flipview inside of HubSection in windows store app

I am trying to auto flip the item of FlipView Items in windows store app. I have tried the following code.

 public MainPage()
        {
            InitializeComponent();

            //Configure the timer
            _timer = new DispatcherTimer
            {
                //Set the interval between ticks (in this case 2 seconds to see it working)
                Interval = TimeSpan.FromSeconds(2)
            };

            //Change what's displayed when the timer ticks
            _timer.Tick += ChangeImage;
            //Start the timer
            _timer.Start();
        }

        /// <summary>
        /// Changes the image when the timer ticks
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="o"></param>
        private void ChangeImage(object sender, object o)
        {
            //Get the number of items in the flip view
            var totalItems = TheFlipView.Items.Count;
            //Figure out the new item's index (the current index plus one, if the next item would be out of range, go back to zero)
            var newItemIndex = (TheFlipView.SelectedIndex + 1) % totalItems;
            //Set the displayed item's index on the flip view
            TheFlipView.SelectedIndex = newItemIndex;
        } 

But i am not able to access the FlipView from .cs file because of the FlipView defined inside of HubSection. How can i solve this? Is there any way of accessing the FlipView or any other way of auto flip the item of FlipView.
