problem solved. has in code-behind:

    public mainpage()     {         this.initializecomponent();         window.current.sizechanged += current_sizechanged;       }      void current_sizechanged(object sender, windows.ui.core.windowsizechangedeventargs e)     {         visualstatemanager.gotostate(this, applicationview.value.tostring(), true);     }
