private void menuitem_canexecute(object sender, canexecuteroutedeventargs e) {     var snd = sender; // main window     var orgsource = e.originalsource; // richtextbox;     var src = e.source; // usercontrol      // think must use command, how?     routedcommand routedcommand = e.command routedcommand; }
