I'm having trouble figuring out how to programmatically setting the "Stroke" of my arrow. I'm using these buttons in a menu bar and I want the one currently selected to have it's arrow change to green and all the others gray.
<Style x:Key="FooterGrayButtonStyle" TargetType="{x:Type Button}">
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="MinHeight" Value="35" />
<Setter Property="FontSize" Value="16"/>
<Setter Property="
Margin" Value="0,5,10,5" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Border x:Name="Bd" Background="#FF535A65" BorderBrush="Black" BorderThickness="1" CornerRadius="10">
<Path x:Name="arrow" Stretch="Fill" Stroke="#FFB1BB1C" StrokeThickness="5" HorizontalAlignment="Right" Margin="5"
StrokeEndLineCap="Round" StrokeStartLineCap="Round" StrokeLineJoin="Miter" Width="13" Height="23" Data="M0,0 L1,1 0,2" />
</Border>
<ContentPresenter HorizontalAlignment="Left" Margin="15,-2,30,0" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="Bd" Property="Background" Value="#FFB1BB1C" />
<Setter Property="Stroke" TargetName="arrow" Value="White"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Stroke" TargetName="arrow" Value="#FFB7B7B7"/>
<Setter Property="Foreground" Value="#FFB7B7B7"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
