코드 뒤에서 실버 라이트로 이미지 바꾸기

Question

나는 실버 라이트 어플리케이션을 만들었습니다. 이미지를 뒤집어서 코드 뒤에 스토리 보드를 만들었습니다. 그러나 오류 "대상 이름을 확인할 수 없습니다."이 표시됩니다.

Storyboard sbFlip = new Storyboard(); 
      sbFlip.Duration = new Duration(TimeSpan.FromSeconds(3)); 
      DoubleAnimationUsingKeyFrames FlipFront = new DoubleAnimationUsingKeyFrames(); 
      DoubleAnimationUsingKeyFrames FlipBack = new DoubleAnimationUsingKeyFrames(); 
      Storyboard.SetTargetName(FlipFront, strFrontSelectedValue); 
      Storyboard.SetTargetName(FlipBack, strBackSelectedValue); 
      Storyboard.SetTargetProperty(FlipFront, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)")); 
      Storyboard.SetTargetProperty(FlipBack, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)")); 
      SplineDoubleKeyFrame sFlipFront = new SplineDoubleKeyFrame(); 
      SplineDoubleKeyFrame sFlipBack = new SplineDoubleKeyFrame(); 
      sFlipFront.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500)); 
      sFlipFront.Value = 0; 
      sFlipBack.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500)); 
      sFlipBack.Value = 1; 
      FlipFront.KeyFrames.Add(sFlipFront); 
      FlipBack.KeyFrames.Add(sFlipBack); 
      sbFlip.Children.Add(FlipFront); 
      sbFlip.Children.Add(FlipBack); 
      sbFlip.AutoReverse = true;    
      sbFlip.Completed += new EventHandler(this.sbFlip_Completed);  
      sbFlip.Begin(); 

나는 어디가 잘못 될까요 ???

와우가 대답을 얻었습니다. 문자열을 이미지로 변환하고 함수에 전달한 다음 대상에 추가하면 이미지가 뒤집 힙니다.

      sFlipBack.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500)); 
      sFlipBack.Value = 1; 
      FlipFront.KeyFrames.Add(sFlipFront); 
      FlipBack.KeyFrames.Add(sFlipBack);

      sbFlip.AutoReverse = true;    
      sbFlip.Completed += new EventHandler(this.sbFlip_Completed);  
      sbFlip.Begin(); 

// 문자열을 전달하고 // 기능

Image imgBack = FindControl<Image>((UIElement)Layout, typeof(Image), strSelectedimg);

Storyboard.SetTarget(FlipFront, imgFront); 
      Storyboard.SetTarget(FlipBack, imgBack);
