c# - Listen for MediaEnded event in another window -

i'm making simple c# wpf video player app.

i have 2 windows: mainwindow (parent window) contains mediaelement display video. playlistwindow (child window) window contains listbox displays .avi files in approot path.

currently, when double-click on listbox item, plays video in mainwindow. have auto-play feature next item in list automatically played when current video ends.

i playlistwindow listen mediaended event triggered mediaelement in mainwindow can perform action on listbox in playlistwindow.

how can subscribe mediaended event playlistwindow?

edit add: ended using different approach shown below. don't think best way it, works me.

public partial class mainwindow : window {     playlistwindow plwindow = new playlistwindow();      public mainwindow()     {         initializecomponent();     }      private void mainwindow_loaded(object sender, routedeventargs e)     {         plwindow.owner = this;         plwindow.show();     }      private void videowindow_ended(object sender, eventargs e)     {         plwindow.playnext();     } }  public partial class playlistwindow : window {     public void playnext()     {         if (playlistbox.selectedindex < playlistbox.items.count - 1)         {             playlistbox.selectedindex = playlistbox.selectedindex + 1;         }         else { playlistbox.selectedindex = 0; }          (owner mainwindow).playvideo(playlistbox.selectedvalue.tostring());     } } 

i'm still open learning how listen mediaended event in playlistwindow if code sample can posted.

raise custom .net event main window(this custom event raised media ended event) , subscribe in playlist window, in event handler of event return file name of next .avi file
