i created new window phone call using next code:

nieuwsimulatie niewsimulatiewindow = new nieuwsimulatie() { owner = }; bool? simulatieaangemaakt = niewsimulatiewindow.showdialog();

in window "nieuwsimulatie" i'd have same datacontext in mainwindow, or databind controls straight datacontext using relativesource geuss, ive tried:

<controls:splitbutton x:name="projectnaam" displaymemberpath="projectnaam" itemssource="{binding static.projecten, relativesource={relativesource mode=findancestor, ancestortype=controls:metrowindow}}"/>

but doesn't work.
