I made this style for my button and it is loaded fine

but I now try to have a different background depending on the IsEnabled property and this does not seem to work

<SolidColorBrush x:Key="Color" Color="#FFADD2CC"/>
<SolidColorBrush x:Key="Color_Disabled" Color="#FF8D9B98"/>

<Style x:Key="ButtonStyle" TargetType="Button">
    <Setter Property="Height" Value="32"/>
    <Setter Property="Padding" Value="8,4,8,4"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="FontWeight" Value="Bold"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border Background="{TemplateBinding Background}">
                    <Grid>
                        <Rectangle x:Name="BackgroundRect" Fill="{StaticResource Color}" RadiusX="2" RadiusY="2"/>
                        <ContentPresenter Margin="{TemplateBinding Padding}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </Grid>
                </Border>
                <ControlTemplate.Triggers>
                    <!-- DataTrigger to change the background color based on IsEnabled property -->
                    <DataTrigger Binding="{Binding IsEnabled, RelativeSource={RelativeSource TemplatedParent}}" Value="True">
                        <Setter TargetName="BackgroundRect" Property="Fill" Value="{StaticResource Color}"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding IsEnabled, RelativeSource={RelativeSource TemplatedParent}}" Value="False">
                        <Setter TargetName="BackgroundRect" Property="Fill" Value="{StaticResource Color_Disabled}"/>
                    </DataTrigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

I use it in my main template like this

<Button Grid.Column="1" Content="Button Text" ToolTip="Some tooltip" Click="OnClick" Style="{StaticResource ButtonStyle}" Margin="0,0,4,0" IsEnabled="false"/>

I expect the button to be a different color depending on the IsEnabled value

thanks for your help
