CheckListBox does not allow vertical item layout with horizontal overflow

[cwenger]

I would like a CheckListBox that stacks items vertically until the space is exhausted, and then continues at the top-right. For example, I can do the following with a plain ListBox in native WPF:

    <ListBox Height="50" Width="100" ScrollViewer.VerticalScrollBarVisibility="Disabled">
        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <WrapPanel Orientation="Vertical" />
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
        <ListBoxItem Content="A" />
        <ListBoxItem Content="B" />
        <ListBoxItem Content="C" />
    </ListBox>

When I try the same with a CheckListBox, it seems to ignore the disabling of the vertical scroll bar (the ItemsPanel seems to be followed because changing the WrapPanel orientation has an effect):

    <xceed:CheckListBox Height="50" Width="100" ScrollViewer.VerticalScrollBarVisibility="Disabled">
        <xceed:CheckListBox.ItemsPanel>
            <ItemsPanelTemplate>
                <WrapPanel Orientation="Vertical" />
            </ItemsPanelTemplate>
        </xceed:CheckListBox.ItemsPanel>
        <ListBoxItem Content="A" />
        <ListBoxItem Content="B" />
        <ListBoxItem Content="C" />
    </xceed:CheckListBox>

Is this a bug? Is there any way to achieve the desired item layout with a CheckListBox?

Hi,

For now, there is no easy way since the CheckListBox's default ControlTemplate uses an ItemsPresenter.
You best option would be to redefine the ControlTemplate to use a WrapPanel. Maybe something like:

<Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:CheckListBox}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <ScrollViewer Padding="{TemplateBinding Padding}" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto"> <StackPanel> <prim:SelectAllSelectorItem x:Name="PART_SelectAllSelectorItem" Content="{TemplateBinding SelectAllContent}" Visibility="{Binding IsSelectAllActive, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource BoolToVisibilityConverter}}" /> <!--<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>--> <WrapPanel IsItemsHost="True" Orientation="Vertical" Height="{TemplateBinding Height}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" /> </StackPanel> </ScrollViewer> </Border> </ControlTemplate> </Setter.Value> </Setter>

Thanks
