设置ListBox的滚动条位置

我可以以编程方式设置WPF ListBox的滚动条的位置吗？默认情况下,我希望它在中心.

要在ListBox中移动垂直滚动条,请执行以下操作:

命名列表框(x:Name ="myListBox")

为Window添加Loaded事件(Loaded ="Window_Loaded")

使用方法实现Loaded事件:ScrollToVerticalOffset

这是一个工作样本:

XAML:

  
    
      
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
        Zamboni
      
    
  

C#

private void Window_Loaded(object sender, RoutedEventArgs e)
{
  // Get the border of the listview (first child of a listview)
  Decorator border = VisualTreeHelper.GetChild(myListBox, 0) as Decorator;
  if (border != null)
  {
    // Get scrollviewer
    ScrollViewer scrollViewer = border.Child as ScrollViewer;
    if (scrollViewer != null)
    {
      // center the Scroll Viewer...
      double center = scrollViewer.ScrollableHeight / 2.0;
      scrollViewer.ScrollToVerticalOffset(center);
    }
  }
}
