Get the item doubleclick event of listview

I'm using something like this to only trigger on ListViewItem double-click and not for example when you double-click on the header of the ListView.

private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DependencyObject obj = (DependencyObject)e.OriginalSource;

    while (obj != null && obj != myListView)
    {
        if (obj.GetType() == typeof(ListViewItem))
        {
            // Do something here
            MessageBox.Show("A ListViewItem was double clicked!");

            break;
        }
        obj = VisualTreeHelper.GetParent(obj);
    }
}

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <EventSetter Event="MouseDoubleClick" Handler="listViewItem_MouseDoubleClick" />
    </Style>
</ListView.ItemContainerStyle>

The only difficulty then is if you are interested in the underlying object the listviewitem maps to e.g.

private void listViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    ListViewItem item = sender as ListViewItem;
    object obj = item.Content;
}
