private void statusExpander_Collapsed ( object sender, RoutedEventArgs e ) {
               GetCheckedOptionList ();
                if ( SpaceStatusCheckedEvent != null ) {
                    SpaceStatusCheckedEvent ( sender, new EventArgs<List<EndpointStatus>> { Data =      lsCheckedOption, Ex = null } );
                }
        }
    }
}




When the statusExpander_Collapsed is called i have some functionality to be done.. but it shud be done after the dropdown is closed.. Now it is cald and the dropdown is stuck,after the functionality is done the dropdown gets closed.
