RadNavigation

Why would you include a FindNodeByText function, but not include a FindNodeByID function?  You allow an ID to be assigned to a NavigationNode...logic dictates you should be able to find it by the ID.

Hello SSirica,

The nodes can have an ID and they can be accessed directly by it. That is why having a FindById method would be redundant. 

On the other hand, if for some reason such access is not possible, you can LINQ to find a node by any property or attribute, or a simple foreach loop:
