WPF中ListBox的WrapPanel布局

<UserControl

<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemTemplate>
<DataTemplate>
<Border Margin="5"/>
</DataTemplate>
</ListBox.ItemTemplate>

<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>

<ListBoxItem Width="100" Height="100" Margin="5" Content="1"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="2"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="3"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="4"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="5"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="6"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="7"/>
<ListBoxItem Width="100" Height="100" Margin="5" Content="8"/>

</ListBox>
</UserControl>

======================================================

如果排出来是纵向列表，原因是Theme错了

如我用的ExpressionDark.xaml作为Theme，修改710行

<StackPanel Margin="1,1,1,1" IsItemsHost="true" />

改为

<ItemsPresenter Margin="1,1,1,1"/>
