Access xaml control inside ith item in flipview

Question

I have a flipview which is populated by some code (I don\'t understand how modifying an app).

You need a VisualTreeHelper method. This is just some code I am using. I think you can easily adjust it to your needs.

First put the FindElementByName method somewhere into your code behind file:

public T FindElementByName<T>(DependencyObject 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<T>(child, sChildName);

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

Now you can start using the method:

this.UpdateLayout();
var fvItem = this.ArticleDetail.Items[ArticleDetail.SelectedIndex];
var container = this.ArticleDetail.ContainerFromItem(fvItem);
// NPE safety, deny first
if (container == null)
    return;
var tbFeedURL = FindElementByName<TextBlock>(container, "FeedUrl");
// And again deny if we got null
if (tbFeedURL == null)
    return;
/*
  Start doing your stuff here.
*/
