c# - Which's differently on isfullscreen and isfullwindows on media player framework? -

<mmppf:mediaplayer x:name="youtubeplayer" visibility="visible" isfullscreenvisible="true"  isfullscreenchanged="youtubeplayer_isfullscreenchanged"  stretch="uniformtofill" mediaquality="highdefinition"  isresolutionindicatorvisible="true" issignalstrengthvisible="false" isaudioselectionvisible="true" isplaypausevisible="true"  isskipaheadvisible="true" isskipbackvisible="true"  mediaopened="youtubeplayer_mediaopened"  mediaended="youtubeplayer_mediaended"  mediaqualitychanged="youtubeplayer_mediaqualitychanged" ></mmppf:mediaplayer>  private async void youtubeplayer_isfullscreenchanged(object sender, routedpropertychangedeventargs<bool> e)     {         try         {          }         catch(exception ex)         {             var dialog = new messagedialog(ex.message);             dialog.showasync();         }      } 

1. isfullwindows = true

   then video plays on fullwindow lost control(play,pause...) athough had touch on screen.

2. isfullscreen ==true

   it not play on fullwindows because of media player framework lies inside grid.

means <grid width=300 height=400> , media player framework play fullsreen of grid(media player framework.width=300...)

note: on xaml getting grid tags

my ways create new pages , show video. don't want that. bad.

how solve it? want play on fullwindow still keep control(play, pause...).
