[ResourceDictionary]동적으로 어플리케이션 리소스 적용하기

MS 예제 실행화면

로그인 사용자를  선택할때마다 배경 밑 컨트롤의 스타일이 바뀐다.

 

프로젝트구성

Resources_*.xaml 파일은 각각의 컨트롤의 스타일을 가지고 있다.

예로 버튼의 스타일을 보면

각각 버튼의 스타일이 다른것을 알수있다.

비하인드 코드에서 적용하기

특별한거 없고 ResourceDictionary 생성해서

            switch (UserTilesListBox.SelectedIndex)
            {
                case 0:
                    Application.Current.Resources = _defaultTheme;
                    break;

                case 1:
                    Application.Current.Resources = _lunaTheme;
                    break;

               case 2:
                   Application.Current.Resources = _xBoxTheme;
                   break;

                case 3:
                    Application.Current.Resources = _toonsTheme;
                    break; 
            }

사용자 선택시마다 리소스를 적용한다.

        ResourceDictionary _toonsTheme ;
        ResourceDictionary _xBoxTheme;

            _toonsTheme = new Resources_Toons();

            Application.Current.Resources = _defaultTheme;
        }

        private void OnMouseEnter(object sender, MouseEventArgs args)
        {
            resourceLoaded = true;
        }
           
        void ChangeUser (object sender, SelectionChangedEventArgs e)
        {

                return;

            switch (UserTilesListBox.SelectedIndex)
            {
                case 0:
                    Application.Current.Resources = _defaultTheme;
                    break;

                case 1:
                    Application.Current.Resources = _lunaTheme;
                    break;

                   break;

                case 3:
                    Application.Current.Resources = _toonsTheme;
                    break; 
            }
        }
    }
