Component Help supports navigation related help pane content and F1 context help via a NavigationItemUIInterface.
Navigation help allow you to associate help with a particular navigation hierarchy in the navigation tree. When a user navigates to that location in the tree then the framework will query you for help for that item. F1 help allows you to supply help in your dialogs and panels that is displayed when the user presses F1.
Navigation Help
To get help appearing in the help pane when the user navigates to an item in the navigation tree you should register a HELP item that has the tree item Navigation Path as it's sub path. e.g.
If the navigation tree item was registered with the path NAVIGATIONTREE\ControlPanel\MyComponent then the path you need to use for the help item is HELP\NAVIGATIONTREE\ControlPanel\MyComponent
In order to ensure the paths match, you can get the navigation path for the tree item with NavGetItem and use the strFQN field as the path passed to NavInsertItem for the help item. The following example inserts an item under the Control Panel item in the tree and associates dynamic help with it.
The NavItemHelpers code in sdk\helpers has more convenient ways to manage navigation items.
