c# - Listview inside of scrollviewer prevents scrollviewer scroll

I have a scrollviewer with a couple listboxes in it. The problem is if a user uses the middle mouse roller to scroll the scrollviewer while their mouse is over a listview. The listview scrolls its internal scrollviewer to the bottom and then continues to capture the mouse, preventing the containing scrollviewer from scrolling.

Any ideas on how to handle this?

That happens because the ListView's (ListBox's, actually) content template wraps its items with a ScrollViewer by itself.

The simplest way is to disable it by dropping your own Template for the inside ListView, one that doesn't create a ScrollViewer:

    <ListView>
      <ListView.Template>
        <ControlTemplate>
          <ItemsPresenter></ItemsPresenter>
        </ControlTemplate>
      </ListView.Template>
      ...
    </ListView>

BTW the same happens if you have a ListView inside a ListView (this was my case).
