Getting Base Content of Selected Node

I am using Syncfusion WPF Controls. I have created a project that displays a Radial Tree Diagram.

I'm trying to access the base values listed under Content on the bottom of the picture(Link, LinkID, ParentID, etc).

Picture:

Looking at the NodeSelected event, When I run node.Content.GetType().ToString(), I get my base class model which contains the properties that I want to access.

So I'm not really sure how to get from selecting the Node, to getting the properties of the base class that is the data for the Node.

Hopefully that all makes sense, I'm self taught.

Here is my MainWindow Code:

    {
        Controller controller = new Controller();
        DirectedTreeLayout tree = new DirectedTreeLayout();
        ObservableCollection<Node> nodes = new ObservableCollection<Node>();
        ObservableCollection<Connector> connects = new ObservableCollection<Connector>();
        public MainWindow()
        {
            InitializeComponent();
            InitDiagram();
            controller.AddRoot();
            Link_Grid.ItemsSource = controller.viewmodel.Links;
            SkinStorage.SetVisualStyle(this, "Blend");
            //nodes.ElementAt(0).IsSelected = true;
        }

        private void InitDiagram()
        {
            controller.Init();
            lmWindow.Nodes = nodes;
            lmWindow.Connectors = connects;
            DataSourceSettings settings = new DataSourceSettings();
            settings.DataSource = controller.viewmodel.Links;
            settings.ParentId = "ParentID";
            settings.Id = "LinkID";
            settings.Root = "0";
            lmWindow.DataSourceSettings = settings;
            settings.DataSource = controller.viewmodel.Links;

            lmWindow.LayoutManager = new LayoutManager()
            {
                Layout = new RadialTreeLayout()
            };



            (lmWindow.LayoutManager.Layout as RadialTreeLayout).HorizontalSpacing = 10;
            (lmWindow.LayoutManager.Layout as RadialTreeLayout).VerticalSpacing = 35;



            //lmWindow.Tool = Tool.SingleSelect;

            SelectorViewModel svm = (lmWindow.SelectedItems as SelectorViewModel);
            svm.SelectorConstraints = svm.SelectorConstraints & ~(SelectorConstraints.QuickCommands|SelectorConstraints.Resizer);




            //lmWindow.Constraints = SelectorConstraints.QuickCommands;

            //lmWindow.Constraints = lmWindow.Constraints & ~(GraphConstraints.Draggable | GraphConstraints.Selectable);


    }

        public void NodeSelected(object sender, DiagramEventArgs e)
        {
            Node node = (e.Item as Node);
            string ders = node.Content.GetType().ToString();
            Console.WriteLine(ders);
        }

        }
    }

Solution

Well, I solved my question but I have no idea why it works.

I'm self taught so I just try everything I can think of until it works. I was able to get the base class content I wanted by:

public void NodeSelected(object sender, DiagramEventArgs e)
{
    Node node = (e.Item as Node);
    string ders = ((Link_Map.Classes.Links)(((System.Windows.Controls.ContentControl)(node)).Content)).link;
    Console.WriteLine(ders);
}

Whereas the (node)).Content)).link was the property I wanted, I can now access any of the base class properties from here.

If anyone has a better way, please post!
