UWP: how to get the RightTapped GridView Item

Question

I have a GridView like below

Answer 1

If the SymbolControl in your ItemTemplate is a bit more complex and the elements in it may have their own DataContexts you could get a reference to the parent ListViewItemPresenter using the following helper method and then cast the DataContext of this to your Symbol item:

private void SymbolGridView_RightTapped(object sender, RightTappedRoutedEventArgs e)
{
    ListViewItemPresenter lvi = e.OriginalSource as ListViewItemPresenter;
    if (lvi == null)
        lvi = FindParent(e.OriginalSource as DependencyObject);

    if (lvi != null)
    {
        SymbolItem clickedItem = lvi.DataContext as SymbolItem;
        if (clickedItem != null)
            MyMediaElement.Source = new Uri(this.BaseUri, symbolItem.ExampleAudio);
    }
}

private static T FindParent(DependencyObject dependencyObject) where T : DependencyObject
{
    var parent = VisualTreeHelper.GetParent(dependencyObject);

    if (parent == null) return null;

    var parentT = parent as T;
    return parentT ?? FindParent(parent);
}
