Odpowiedź: Dlaczego nie zmienia się kolor tła przycisku?

Dobra. Już ogarnąłem temat. Może komuś się przyda:

 

<Window.Resources>
        <Style x:Key="Triggersy" TargetType="Button">
            <Setter Property="Background" Value="Brown"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Background" Value="White"/>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
</Window.Resources>
<DockPanel>
    <Button DockPanel.Dock="Left" Content="gngurgoo" Style="{StaticResource Triggersy}" Width="100"/>
</DockPanel>
