Hi,

I have created styled a ListBox in WPF so that it is rendered as a checkbox list.

When I populate the ListBox's items manually, the styling works perfectly. However, when I instead bind the ItemsSource of the ListBox to a static resource (an ItemsControl containing the required items), the styling is completely dropped.

Here's the style:

<Style x:Key="CheckBoxListStyle" TargetType="ListBox">
    <Style.Resources>
        <Style TargetType="ListBoxItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem">
                        <Grid Margin="2">
                            <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="Auto" />
                                    <ColumnDefinition />
                            </Grid.ColumnDefinitions>
                            <CheckBox IsChecked="{Binding IsSelected, RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}"/>
                            <ContentPresenter
                                Grid.Column="1"
                                Margin="2,0,0,0" />
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Style.Resources>
    <Setter Property="ItemsPanel">
        <Setter.Value>
            <ItemsPanelTemplate>
                <WrapPanel Orientation="Vertical"  />
            </ItemsPanelTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="BorderThickness" Value="0" />
    <Setter Property="Background" Value="Transparent" />
</Style>

Here's the code for the ListBox that shows the style correctly:

<ListBox x:Name="ColumnsList"
            Grid.Column="0"
            Grid.Row="0"
            Style="{StaticResource CheckBoxListStyle}"
            BorderThickness="1">                                                
            <ListBox.Items>
                <ListBoxItem>Test</ListBoxItem>
                <ListBoxItem>Test2</ListBoxItem>
                <ListBoxItem>Test3</ListBoxItem>
            </ListBox.Items>
        </ListBox>

Here's the code for the ListBox that ignores the style:

<ListBox x:Name="ColumnsList2"
            Grid.Column="0"
            Grid.Row="0"
            Style="{StaticResource CheckBoxListStyle}"
            BorderThickness="1"
            ItemsSource="{Binding Source={StaticResource Test1}, Path=Items}">
        </ListBox>

Hoping someone can help - I'm pretty new to all this and have tried everything I can think of, but everything I've read leads me to believe that setting ItemsSource should have the same outcome as setting the items manually, so I can't see any reason why this would not work.

Thanks,

AT
