No you can't. Simply because all requests pass through a single action. In order to retrieve a path to a CMS-managed page, you need to use the node/content traversal the @Model provides. See here for more details on this.
Edit
To clarify, the author of the article is suggesting that the Umbraco implementation should be more in line with a traditional MVC implementation with little or no logic in the views. Therefore, any querying of node data should happen prior to the view (e.g. in the Mappers). So this is where you would have to retrieve the links.
Umbraco's default MVC implementation forces all requests to go via a single action on a single controller. The author's implementation allows the requests to be shared across one controller per document type - which is better IMO. But it still means that things like Html.ActionLink are redundant in the views since there isn't an action per page.
Further edit
If you wanted to build a navigation list with a combination of Umbraco-managed pages and non-Umbraco pages, regardless of the implementation, I would:
- Create a child action and view for the navigation in a separate NavigationControllerthat inherits from theSurfaceController
- Use the this.CurrentPageproperty of the inheritedSurfaceControllerto traverse the Umbraco content cache to retrieve the relevant Umbraco-managed pages. You can then use theUrlproperty of each page result to get its path, and theNameproperty to get the page title
- Use this.Url.Action("action", "controller")to retrieve the paths to specific non-Umbraco actions. Alternatively, if the pages are database-managed, use you data layer (e.g. EF, NHibernate, PetaPoco) at this point
- Combine these in a Dictionary to make the list you require where the Keyis the path and theValueis the page title
- Pass this down to the view as the view model.
Of course there any many more things to consider like caching, but in a nutshell, that's a fairly basic implementation.
