wpf - Get owner of context menu on Button -

title says all.i have lot of buttons, of them have same context menu, want determine click event button rgiht clicked there.

this code not work, placementtarget null:

private void mi_click(object sender, routedeventargs e) {         button contextmenuezen = null;          menuitem mnu = sender menuitem;          if (mnu != null)         {             contextmenu ize =(contextmenu)mnu.parent;             contextmenuezen = ize.placementtarget button;         } } 

please me!

routedevents don't work regular events - signature of handler eventhandler(object sender, routedeventargs e). routedeventargs has property called originalsource represents element in ui clicked. in contrast, sender parameter object on event handler registered.
