    the context menu has its own visual tree, try this calling this from your event handler like so :-

    StackPanel stackPanel = GetStackPanelItemFromContextMenu((FrameworkElement)sender, yourStackPanel);
    
      private StackPanel GetStackPanelItemFromContextMenu(FrameworkElement sender, StackPanel stackPanel) {
         Point menuClickPoint = ((sender as FrameworkElement).Parent as ContextMenu).TranslatePoint(new Point(0, 0), stackPanel);
    
         // get the first potential object that was hit   
         DependencyObject obj = stackPanel.InputHitTest(menuClickPoint) as DependencyObject;
    
         // cycle up the tree until you hit the StackPanel
         while (obj != null && !(obj is StackPanel)) {
            obj = VisualTreeHelper.GetParent(obj);
         }
    
         return obj as StackPanel;
      }
