當ScrollViewer里包含很多子控件時，默認情況下只能用鼠標手動拖動(或滾輪)滾動條以實現內容的滾動，假如用戶是鍵盤高手，習慣于用Tab鍵來切換子控件焦點時，即使當前獲得焦點的控件在不可見區域，滾動條也不會自動跟隨著滾動到相應位置，這個非常不方便，今天在網上看到一個老外的解決辦法，代碼轉貼于此：

01 private void _ScrollViewer_GotFocus(object sender, RoutedEventArgs e)

02 {

03 FrameworkElement element = e.OriginalSource as FrameworkElement;

04

05 if (element != null)

06 {

07  ScrollViewer scrollViewer = sender as ScrollViewer;

08 scrollViewer.ScrollToVerticalOffset(GetVerticalOffset(element, scrollViewer));

09 }

10

11 }

12

13 private double GetVerticalOffset(FrameworkElement child, ScrollViewer scrollViewer)

14 {

15 // Ensure the control is scrolled into view in the ScrollViewer.

16 GeneralTransform focusedVisualTransform = child.TransformToVisual(scrollViewer);

17  Point topLeft = focusedVisualTransform.Transform(new Point(child.Margin.Left, child.Margin.Top));

18 Rect rectangle = new Rect(topLeft, child.RenderSize);

19 double newOffset = scrollViewer.VerticalOffset + (rectangle.Bottom - scrollViewer.ViewportHeight);

20 return newOffset < 0 ? 0 : newOffset; // no use returning negative offset

21 }

　　即：給ScrollViewer的GotFocus事件增加_ScrollViewer_GotFocus處理方法，然后計算當前獲取焦點的控件與ScorllViewer的偏移距離，最終得出滾動條應該滾動的偏移量。
