当复选框/单选按钮处于焦点状态时，如何设置样式复选框/单选按钮？

Question

I want to set border for checkbox/radiobutton when it is focused. Here is my code! Thanks

 UIElement element = container;
 DependencyObject obj2 = FocusManager.GetIsFocusScope(element) ? element : 
 FocusManager.GetFocusScope(element);
 IInputElement focusedElement = FocusManager.GetFocusedElement(obj2);
 object obj = focusedElement;

 if (obj != null && (obj.GetType() == typeof(CheckBox) || obj.GetType() == 
     typeof(RadioButton)))
   {
  //Set style when focus for Checkbox, radiobutton. 
   }

Here is the code

 if (obj != null && (obj.GetType() == typeof(CheckBox) || obj.GetType() == 
         typeof(RadioButton)))
       {
         var element = obj as FrameworkElement;
         // element.Style =  Resources["ResourceName"] as Style;
         // or 
         //  element.Style = (Style) FindResource("YourResourceKey");
       }

I commented out the line as these are the ways to set style if defined in resources.
