Question

我有一个包含复选框的列表框 (WPF)。我在配置屏幕中使用。示意图如下:

现在我想添加一个“测试 5”复选框。我的垂直空间有限，所以我想让它出现在水平方向，如下图:

是否可以修改 ListBox 布局，使 CheckBox 像这样排列？

<ListBox Name="CategoryListBox"
         ScrollViewer.HorizontalScrollBarVisibility="Disabled"
         ItemsSource="{Binding Path=RefValues,
                UpdateSourceTrigger=PropertyChanged}"
                SelectionMode="Multiple">
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel />
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBox.ItemTemplate>
        <DataTemplate >
            <StackPanel Orientation="Horizontal"
                        MinWidth="150" MaxWidth="150"
                        Margin="0,5, 0, 5" >
                <CheckBox
                    Name="checkedListBoxItem"
                    IsChecked="{Binding
                            RelativeSource={RelativeSource FindAncestor,
                            AncestorType={x:Type ListBoxItem} },
                            Path=IsSelected, Mode=TwoWay}" />
                <ContentPresenter
                    Content="{Binding
                            RelativeSource={RelativeSource TemplatedParent},
                            Path=Content}"
                    Margin="5,0, 0, 0" />
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

或者像这样简单:

<Grid>
    <ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <WrapPanel IsItemsHost="True" />
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
        <ListBoxItem>listbox item 1</ListBoxItem>
        <ListBoxItem>listbox item 2</ListBoxItem>
        <ListBoxItem>listbox item 3</ListBoxItem>
        <ListBoxItem>listbox item 4</ListBoxItem>
        <ListBoxItem>listbox item 5</ListBoxItem>
    </ListBox>
</Grid>
