HelixViewport3d::SphereVisual3D - How to add children via XAML (and a back end binding)?

Jul 18, 2014 at 6:15 PM
Experts,

I have the back end down. Right now, the XAML is the pain.

Given the following working XAML, how should I implement the backend collection of "Conns" (Connections, or Flights) in the Current Flight Demo code (which this came from)?

Below in the abbreviated XAML, this section toward the bottom is the one in question:
   <ItemsControl ItemsSource="{Binding Conns}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                    <Viewport3D /> <--- ??? or...?
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
    </ItemsControl>
I'm 100% on the backend. I just can't figure out how to make the XAML under Helix3D ready to bind to/show the collection...

Any help at all REALLY appreciated!!!
