Windows Phone 7: Disable Screensaver (lock) during action

In our Windows Phone 7 project we need to disable the screensave (lock) of Windows Phone 7 for example during playing a media file in Mediaelement or during a picture slideshow. To reach this goal you can use the PhoneApplicationService.Current.UserIdleDetectionMode and set it to IdleDetectionMode.Enabled or IdleDetectionMode.Disabled.

 

Sample of a property

   1: public bool SlideshowIsActive

   2:        {

   3:            get { return _slideshowIsActive; }

   4:            set

   5:            {

   6:                if (_slideshowIsActive == value) return;

   7:  

   8:                _slideshowIsActive = value;

   9:  

  10:                PhoneApplicationService.Current.UserIdleDetectionMode = _slideshowIsActive ? IdleDetectionMode.Disabled : IdleDetectionMode.Enabled;

  11:  

  12:                NotifyPropertyChanged(() => SlideshowIsActive);

  13:            }

  14:        }
