Ilnumerics Ilpanel not activating when compiled in a winform into a dll when loaded into matlab

问题

I want to compile a winform written in c# in visual-studio 2012 to a dll which I then load into matlab 2013a. Using the matlab .net interface I want to then interact with the winform, listening to its events and passing it data via a set of predefined public methods. I am working on windows 7 Ultimate SP2.

This works surprisingly well, I am able to interact with all native winform tools, buttons, trees, panels and even charts. However i want to use ILnumerics and particularly the ILpanel used to display "scenes" containing all wonder of things. This is were I hit a brick wall nothing ever gets rendered in the IPanel when it is compiled as a dll and called into matlab. It only ever shows the default oval.

I can attach matlab as a process in visual studio and run through the code. It all executes fine. It looks like the scene on line 32 is not properly attached to iLPanel1.

Any help would be appreciated.

            for (int i = 0; i < myX.Length; i++)
            {
                myDoubleVec[i] = myX[i, 0];
            }

            var scene = new ILScene();

            PlotData(myDouble);
        }

        public void PlotRandom()
        {
            double yValue = 50.0;
            double yValue2 = 200.0;

            }
            Random random = new Random();

                chart1.Series["Series1"].Points.AddY(yValue);

                yValue2 = yValue2 + (float)(random.NextDouble() * 10.0 - 5.0);
                chart1.Series["Series2"].Points.AddY(yValue2);

        private void button1_Click(object sender, EventArgs e)
        {
            PlotRandom();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            var myDouble = new double[,] { { 2 }, { 4 }, { 6 }, { 8 } }; ;
            PlotData(myDouble);
        }
    }
}

The resulting winform looks as follows.

Matlab code to load assembly and manipulate the form.

 NET.addAssembly('C:\Users\philliproso\Documents\Visual Studio 2012\Projects\WindowsFormsApplication3\WindowsFormsApplication3\bin\Debug\WindowsFormsApplication3.dll')
    myForm=WindowsFormsApplication3.Form1;
    myForm.Show;
    myForm.plotRandom; %this call works fine
    myForm.PlotData(rand(50,1)); %this call has no effect
