WPF ListBox scrollbar is not working
提问by Stacked
<ListBox Name="myListBx" ItemsSource="{Binding Collection}" Margin="5,5"
SelectedValuePath="ColId"
SelectedValue="{Binding Path=ColId}"
SelectionMode="Multiple"
BorderThickness="0" Background="{x:Null}" BorderBrush="{x:Null}"
ScrollViewer.VerticalScrollBarVisibility ="Auto">
<ListBox.ItemTemplate>
<DataTemplate>
// blabla
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
My ListBox contains so many elements and actually the scrollbar should work but it's not even visible. Am I doing something wrong?
我的 ListBox 包含这么多元素，实际上滚动条应该可以工作，但它甚至不可见。难道我做错了什么？
Thanks
谢谢

You need to put the ListBox in a Grid. The StackPanel has an
infinite height, so that the ScrollBar does not get enabled or visible.
您需要将 ListBox 放在 Grid 中。StackPanel 具有
无限高度，因此 ScrollBar 不会被启用或可见。
<Grid>
<ListBox VerticalAlignment="Stretch" />
</Grid>
