Zdravím, mám UserControl, který renderuju a poté uložím do souboru. Jenže nějak divně tam funguje binding. Když ten usercontrol použiju normálně ve stránce (phone:PhoneApplicationPage), tak to jde, ale když v kódu vytvořím ten můj control, tak to už nefunguje. Tak nějak to vypadá: http://imgup.cz/images/2013/10/05/zx3Sb.... MainPage.xaml
