平板电脑 WPF Windows 桌面应用程序 - 滚动问题 [英] Tablet WPF Windows Desktop Application - Scrolling issue

问题描述

我正在平板电脑 ASUS ME400 Intel Atom Z2760 上运行我的桌面应用程序 WPF.一切正常，但是当我使用 scrollviewer 时，在用手指滚动结束时用手指滚动移动(仅限水平平移模式)，窗口移动，您会看到任务栏片刻.用手指滚动没有看到效果，直到在滚动条中找到才到达.

I'm running my desktop application WPF on tablet ASUS ME400 Intel Atom Z2760. All working properly, but when I use scrollviewer, scroll movement with finger (abilitate panning mode horizontalOnly) at the end of scroll with finger, the window moves and you see the taskbar for a moment. The effect is not seen if I scroll with my finger, did not arrive until founded in the scrollbar.

我怎样才能避免这个窗口移动?如何在滚动条末尾滚动时锁定我的窗口并且不允许移动?

How i can avoid this window movement? How I can lock my windows and do not permit to move when I scroll at the end of scrollbar?

推荐答案

在启用平移的 ScrollViewer 对象中，为 ManipulationBoundaryFeedback 注册一个新事件.

In the ScrollViewer object, where you've enabled the panning, register a new event for ManipulationBoundaryFeedback.

<ScrollViewer PanningMode="Both" ManipulationBoundaryFeedback="ScrollViewer_ManipulationBoundaryFeedback">
    <!-- your content is here... -->
</ScrollViewer>

在代码隐藏中，您必须通过将 Handled 属性设置为 true 来处理事件:

In the codebehind, you have to handle the event, by setting the Handled property to true:

void ScrollViewer_ManipulationBoundaryFeedback(object sender, ManipulationBoundaryFeedbackEventArgs e)
{
    e.Handled = true;
}

(通过将 Handled 属性设置为 true，我们实际上是在告诉我们该事件已由我们处理，因此我们正在停止消息的冒泡过程在可视化树中，在它到达 Window/Application 之前 - 以引起震动的为准.)

(By setting the Handled property to true, we are actually telling that the event has got handled by us, so we are stopping the message's bubbling process in the Visual Tree, before it would reach the Window/Application - whichever would cause the shaking.)
