Summary0001467: ScrollViewer mouse wheel scroll does not work if the mouse is over a child ScrollViewer
DescriptionThere is a problem with ScrollViewer on element inside another ScrollViewer. If mouse hovers on child ScrollViewer, parent ScrollViewer don't get mouse-wheel-scroll, even if child has nothing to scroll and scrollbars on it are invisible

if after the start of scrolling the cursor is over the element containing the ScrollViewer, then the scrolling is frozen

P.S.
Checked in WPF, similar behavior. How to make scrolling in this case?

Hi,

Yes, this is the behavior of WPF also.
Usually when you have nested lists, the inner one doesn't need to scroll. So the solution is to provide a different template for that inner list that doesn't have a ScrollViewer.
This way the wheel event will reach the outer list's ScrollViewer without problems.

Could you try that?
