CheckListBox does not allow vertical item layout with horizontal overflow about wpftoolkit HOT 1 OPEN

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
