2. 逐项指标
原标题:Get the item index which is on focus inside a stackpanel

我在一次滚动式访谈中增加了10个图像。 当用户冲动网页时,如果浏览器停在“安放”上,则该浏览器停在某个位置上;图像一想获得图像的名称。 如何做到这一点?

      for (int i = 0; i <= 59; i++)
        {

  Uri uri = new  Uri("http://d1mu9ule1cy7bp.cloudfront.net/2012/media/catalogues/47/pages/p_" + i + "/thump.jpg");
            ImageSource img1 = new BitmapImage(uri);
            Image rect = new Image { RenderTransform = new TranslateTransform() };

            rect.Source = img1;

            stack.Children.Add(rect);

        }

XAML:

<ScrollViewer HorizontalContentAlignment="Left" HorizontalAlignment="Left" Name="scroll" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Visible">

        <StackPanel Name="stack" Width="Auto" Orientation="Horizontal" HorizontalAlignment="Left"  >

    </StackPanel>
    </ScrollViewer>

假设你的图像规模相同,你可以参考浏览器
