Ni:graph fails in WPF with events

I a trying to create an interface that implements a Measurement Studio 2013 graph in Visual Studio 2015.

I have successfully added the graph to the form and tested it for about a week, but now I'm trying to add a custom pull out menu to the same form. If I comment out the graph, the project builds and runs as intended. If I disable the events that fire the pull out menu and add the graph back in, the program runs as intended, But if the two are on the form at the same time, I get a XAML Parse error on my last closing .

If I investigate the inner exceptions, I arrive at a NationalInstruments.Control 'Specified Method is not Supported' error.

narrowing it down further, if I removed the event trigger's SourceName property, the project builds, but of course the events no longer fire properly.

<Window.Triggers><EventTriggerRoutedEvent="ToggleButton.Checked"SourceName="btnExpand"><BeginStoryboardStoryboard="{StaticResource ExpandisChecked}"/></EventTrigger><EventTriggerRoutedEvent="ToggleButton.Unchecked"SourceName="btnExpand"><BeginStoryboardStoryboard="{StaticResource ExpandisUnChecked}"/></EventTrigger></Window.Triggers>

Making the above into:

<Window.Triggers><EventTriggerRoutedEvent="ToggleButton.Checked"><BeginStoryboardStoryboard="{StaticResource ExpandisChecked}"/></EventTrigger><EventTriggerRoutedEvent="ToggleButton.Unchecked"><BeginStoryboardStoryboard="{StaticResource ExpandisUnChecked}"/></EventTrigger></Window.Triggers>

clears the error but doesn't provide functionality.

there stack trace shows:

How can I have both on the form at the same time?

here is the full code for the window if it helps:
