Actually, mmNavigationToolStrip is not intended to be dropped directly on a form. It appears automatically on the current form or on the main mdi form based on the setting of the form's DisplayNavigationToolbar property. Check out the MM .NET Dev Guide topic "Adding a Navigation ToolStrip to your Forms" for details.
