如何让 ScrollViewer 将 Click 事件传递到其背后的控件？
我有两个相互重叠的网格，顶层位于 ScrollViewer 中。问题是底层有点击事件，并且它们不会被那里的 ScrollViewer 触发。
有没有办法让ScrollViewer将点击事件传递给它后面的控件？
<Grid>
<local:MyBackgroundControlWithClickEvents />
<ScrollViewer>
<local:MyForegroundControlWithClickEvents />
</ScrollViewer>
</Grid>
I have two grids overlaying one another, and the top layer is in a ScrollViewer. The problem is the bottom layer has click events, and they don't get triggered with the ScrollViewer there.
Is there a way to have the ScrollViewer pass click events to the control behind it?
<Grid>
<local:MyBackgroundControlWithClickEvents />
<ScrollViewer>
<local:MyForegroundControlWithClickEvents />
</ScrollViewer>
</Grid>

单击事件将可视化树向上冒泡到根，因为您的控件是不是
ScrollViewer的父级，它不会接收这些事件。我知道它们可能在屏幕上重叠，但就视觉树而言，它们是兄弟姐妹，而不是父/子。要实现此目的，您可以将
MyBackgroundControlWithClickEvents更改为ContentControl并在其中托管ScrollViewer。Click events bubble up the visual tree to the root, because your control is not a parent of the
ScrollViewer, it will not receive these events. I know they might overlap on screen, but as far as the visual tree is concerned they are siblings, not parent / child.To make this work, you could change
MyBackgroundControlWithClickEventsinto aContentControland host theScrollViewerwithin it.
