How to get a top object (Window or Page) in WPF? [duplicate]

Answer 1

You can use the VisualTreeHelper class to retrieve the top-level control :

DependencyObject GetTopLevelControl(DependencyObject control)
{
    DependencyObject tmp = control;
    DependencyObject parent = null;
    while((tmp = VisualTreeHelper.GetParent(tmp)) != null)
    {
        parent = tmp;
    }
    return parent;
}
