WPF触屏激活滚动条

// XAML代码
<ScrollViewer PanningMode="Both" ManipulationBoundaryFeedback="ScrollViewer_ManipulationBoundaryFeedback">
</ScrollViewer>

// CS代码，添加ManipulationBoundaryFeedback事件防止拖动抖动
private void ScrollViewer_ManipulationBoundaryFeedback(object sender, ManipulationBoundaryFeedbackEventArgs e)
{
    e.Handled = true;
}
