How to Implement Help for the Customization Form
To include your own custom help for the Customization Form, you should use the Help button placed at the bottom of this form. By default, the Help button is hidden. To make it visible, set the ShowHelpButton property of the bar manager to True. Use the HelpButtonGlyph property to specify the picture drawn on the Help button.
Additionally, you should write an OnHelpButtonClick event handler which responds to the Help button click.
