How to Get element inside the content control

Question

I need to find the element inside the content control :

Answer 1

This method will help you:

public T FindElementByName(FrameworkElement element, string sChildName) where T : FrameworkElement
    {
            T childElement = null;
            var nChildCount = VisualTreeHelper.GetChildrenCount(element);
            for (int i = 0; i < nChildCount; i++)
            {
                FrameworkElement child = VisualTreeHelper.GetChild(element, i) as FrameworkElement;

                if (child == null)
                    continue;

                if (child is T && child.Name.Equals(sChildName))
                {
                    childElement = (T)child;
                    break;
                }

                childElement = FindElementByName(child, sChildName);

                if (childElement != null)
                    break;
            } 
            return childElement;
    }

And, how I use it, just add button, and on button Click:

 private void Button_OnClick(object sender, RoutedEventArgs e)
    {
        var element = FindElementByName(ccBloodGroup, "cbBloodGroup");
    }
