If you are finding this question and the VisualTreeHelper isn't working for you or working sporadically, you may need to include LogicalTreeHelper in your algorithm.

Here is what I am using:

public static T TryFindParent(DependencyObject current) where T : class
{
    DependencyObject parent = VisualTreeHelper.GetParent(current);
    if( parent == null )
        parent = LogicalTreeHelper.GetParent(current);
    if( parent == null )
        return null;

    if( parent is T )
        return parent as T;
    else
        return TryFindParent(parent);
}
