I have this layout:
<ScrollViewer>
<StackPanel>
<ListView>
<ListView.View>
<GridView>
<!-- Content -->
</GridView>
</ListView.View>
</ListView>
<!-- Filtering Controls -->
</StackPanel>
</ScrollViewer>
The screen doesn't have a fixed or max height. The Scrollbar shows fine and works fine, but when the mouse is over the items in the List/GridView, the ScrollViewer doesn't receive the event and doesn't scroll.
I've read about how I can implement an extension, but that seems overdoing it, what's the simplest solution to make the List/GridView either pass the mouse wheel scroll event to the ScrollViewer or ignore them?
