In your samplecode for "UltraNavigationBar" is the class "DirectoryWrapper" used. I don't know the assembly or namespace. Please, can you help me?

 === Infragistics Samplecode ===============================================================

> public class FileSystemSupport

> public void Populate()....

>                  //  Assign an instance of a wrapper class which associates the node,
>                   //  location and directory to each object to the Tag property.
>                   node.Tag = new DirectoryWrapper( drive.RootDirectory, location );
>                   location.Tag = new DirectoryWrapper( drive.RootDirectory, node );

==================================================================

Error :

Error 2 The type or namespace name 'DirectoryWrapper' could not be found (are you missing a using directive or an assembly reference?)
