I'm new to WPF and I am stuggling to find the solution to what I'm trying to do as I'm still a little uncertain as to whether I'm doing this correctly.

I have the following style defined for a button

<Style x:Key="ToolBarButtonStyle" TargetType="{x:Type Button}"> <Setter Property="Margin" Value="5" /> <Setter Property="BorderBrush" Value="White" /> <Setter Property="Background" Value="{DynamicResource CompanyBlue}" /> <Setter Property="Foreground" Value="White" /> <Setter Property="FontWeight" Value="Bold" /> <Setter Property="FontSize" Value="20" /> <Setter Property="Width" Value="100" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Border x:Name="ButtonBorder" BorderThickness="5" CornerRadius="5" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" Width="{TemplateBinding Width}"> <ContentPresenter Margin="10" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Border> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Button.Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,-0.2" EndPoint="0,1.2"> <LinearGradientBrush.GradientStops> <GradientStop Color="White" Offset="0" /> <GradientStop Color="{ORIGINAL-COLOR}" Offset="0.5" /> <GradientStop Color="White" Offset="1" /> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> 

In the XAML, where I have put the placeholder {ORIGINAL-COLOR}, I essentially want this to be the value that is used previously set with {TemplateBinding Background} for the control template of the style.

I've seen suggestions that I should use {Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background} but this is not working.

Thanks in advance for any help.
