ItemsControl missing vertical scrollbar
提问by touyets
I have the below ItemsControlwhich wraps items perfectly but it does not have a vertical scrollbar to see the wrapped items. How can I get the scrollbar to show?
我有下面的ItemsControl东西可以完美地包裹物品，但它没有垂直滚动条来查看包裹的物品。如何让滚动条显示？
<ItemsControl x:Name="tStack" Grid.Column="0" Grid.Row="1"
ItemsSource="{Binding Shows.View}"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
BorderThickness="0.5">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal" HorizontalAlignment="Left"
VerticalAlignment="Top"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Viewbox HorizontalAlignment="Left" Height="250">
<Controls1:MyShowsUserControl Padding="10"/>
</Viewbox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

ItemsControlby default does not wrap ItemsPresenterin ScrollViewerso you have to do it manually like so:
ItemsControl默认情况下不换行ItemsPresenter，ScrollViewer因此您必须像这样手动完成：
<ScrollViewer Grid.Column="0" Grid.Row="1">
<ItemsControl x:Name="tStack" ... >
<!-- .... -->
</ItemsControl>
</ScrollViewer>

Wrap your ItemsControlin a ScrollViewercontrol.
将您包裹ItemsControl在一个ScrollViewer控件中。
<ScrollViewer VerticalScrollBarVisibility="Auto">
<ItemsControl ...
</ScrollViewer>
Remember to put the Grid.Column="0" Grid.Row="1"attributes in the ScrollViewer instead of in your ItemControl.
请记住将Grid.Column="0" Grid.Row="1"属性放在 ScrollViewer 中，而不是放在 ItemControl 中。

Use ScrollViewer and set the property "VerticalScrollBarVisibility" true.
使用 ScrollViewer 并将属性“VerticalScrollBarVisibility”设置为 true。
< ScrollViewer VerticalScrollBarVisibility="Auto">
< ScrollViewer VerticalScrollBarVisibility="Auto">
Here your ItemsControl
在这里你的 ItemsControl
