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

i want compile winform written in c# in visual-studio 2012 dll load matlab 2013a. using matlab .net interface want interact winform, listening events , passing data via set of predefined public methods. working on windows 7 ultimate sp2.

this works surprisingly well, able interact native winform tools, buttons, trees, panels , charts. want use ilnumerics , particularly ilpanel used display "scenes" containing wonder of things. hit brick wall nothing ever gets rendered in ipanel when compiled dll , called matlab. ever shows default oval.

i can attach matlab process in visual studio , run through code. executes fine. looks scene on line 32 not attached ilpanel1.

any appreciated.

form1.cs primary c# code without form1.designer.cs

the resulting winform looks follows.

matlab code load assembly , manipulate 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
