Get navigation items in DevExpress eXpressApp Framework (XAF) application

Question

I have a eXpressApp Framework (XAF) desktop application. The main window contains Navigation pane with tree of items. Is there any way to obtain the list of navigation items in code?

Answer 1

a XAF application model can be extended using interfaces. It is really easy to extend it and intentify it. For example in your situation I would open the model using ModelEditor and navigate to the NavigationItems node. When there you can look at the yellow info panel at the bottom of your form it says *Member of interface:*DevExpress.ExpressApp.SystemModule.IModelApplicationNavigationItems

This means that that XAF extended the model using the IModelApplicationNavigationItems, so we all need to do is to cast it to that interface and use its properties.

((IModelApplicationNavigationItems) Application.Model).NavigationItems.AllItems

This approach has the same result as yours, however is strongly bound!

Answer 2

It was not easy to find, but here is the solution:

var navigationItems = Application.Model.GetNode<IModelRootNavigationItems>("NavigationItems").AllItems;

Answer 3

Your code is suitable to get the list of navigation elements from the application model (a meta data tier). Alternatively, you can access the same information from the ShowNavigationItemController.ShowNavigationItem.Items property.
