禁用ScrollViewer的Horizo​​ntalScrollMode并在父级中接收操作事件 [英] Disable HorizontalScrollMode of ScrollViewer and receiving Manipulation events in the parent

问题描述

我有一个垂直滚动的ScrollViewer（Horizo​​ntalScrollMode =" Disabled"），我需要按顺序监听父元素中的Manipulation事件水平滚动。问题是父进程中没有引发操作事件。

I have a ScrollViewer which scrolls vertically(HorizontalScrollMode="Disabled"), and I need to listen to the Manipulation events in a parent element in order to scroll horizontally. The problem is that the manipulation events are not raised in the parent.

我已经在ScrollViewer中检查了设置IsHitTestVisible = False，在父进程中正确接收了事件，我也试过了在Scrollviewer中设置ManipulationMode = None但没有成功。

I already checked that setting IsHitTestVisible=False in the ScrollViewer, the events are properly received in the parent, and I also tried setting ManipulationMode=None in the Scrollviewer with no success.

提前致谢，

Alvaro。

推荐答案

ScrollViewers和ManipulationMode没有他们看起来可能的确切关系，滚动是不同的。问题 相反，对于您所描述的场景，它听起来就像您想要的是Scroll Chaining。

ScrollViewers and ManipulationMode don't have the exact apparent relationship they may seem to, Scrolling is a different issue.  Rather, for the scenario you're describing it sounds like what you want is Scroll Chaining.

对于你所描述的内容，尤其是"父元素水平滚动"这样的事情最有意义：

For what you've described, especially "parent element scrolling horizontally" something like this makes the most sense:

        <ScrollViewer Width="500" Height="500" Background="Green" HorizontalScrollMode="Enabled"  HorizontalScrollBarVisibility="Auto">
            <ScrollViewer Width="1600" Background="Red" Margin="20" Height="600" IsHorizontalScrollChainingEnabled="True">
                <Ellipse Fill="Blue" Height="1000" />
            </ScrollViewer>
        </ScrollViewer>

如果不这样做，请发送一个repro项目或代码/标记我很乐意提出更多建议。

Failing that, send a repro project or code/markup and I'll gladly make more suggestions.
