Почему не удаётся использовать полосу прокрутки в ListView?

Question

Она отображается, но ею нельзя пользоваться . Из-за чего это может быть ?

  <StackPanel Margin="10 0 10 0">

            <ScrollViewer IsEnabled="True" VerticalScrollBarVisibility="Visible">

Answer 1

Всё, поправил косяк обернул StackPanel в <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">

ну и закрывающий тег в конце

Касаемо прокрутки = (если не наведена мышка на скролл, то вот код)

в xmal создаём событие PreviewMouseWheel="ScrollViewer_PreviewMouseWheel"

ScrollViewer scv = (ScrollViewer)sender;
        scv.ScrollToVerticalOffset(scv.VerticalOffset - e.Delta / 3);
        e.Handled = true;
