How to reuse behaviors? - xaml

Question

Have two behaviors that change a path's opacity based on its container button's IsEnabled property. I have several buttons that I want to reuse these two behaviors for that have the same path up to their containers. How do I do that?
<Button x:Name="buttonConcentration">
<Canvas Width="42.6667" Height="42.6667">
<Path Opacity="0.2" Width="42.835" Height="42.696" Stretch="Fill"
Data="..." UseLayoutRounding="False">
<Interactivity:Interaction.Behaviors>
<Core:DataTriggerBehavior
Binding="{Binding IsEnabled, ElementName=buttonConcentration}"
Value="False">
<Core:ChangePropertyAction PropertyName="Opacity" Value="0.2"/>
</Core:DataTriggerBehavior>
<Core:DataTriggerBehavior
Binding="{Binding IsEnabled, ElementName=buttonConcentration}"
Value="True">
<Core:ChangePropertyAction PropertyName="Opacity" Value="1"/>
</Core:DataTriggerBehavior>
</Interactivity:Interaction.Behaviors>
</Path>
</Canvas>
</Button>

Try setting it on your Window.Resources.
Maybe working over this code you'll be able to achieve what you are expecting:
<Window.Resources>
<Button x:Key="myButtonConcentration" x:Shared="False">
<Canvas Width="42.6667" Height="42.6667">
<Path Opacity="0.2" Width="42.835" Height="42.696" Stretch="Fill"
Data="..." UseLayoutRounding="False">
<Interactivity:Interaction.Behaviors>
<Core:DataTriggerBehavior
Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsEnabled}"
Value="False">
<Core:ChangePropertyAction PropertyName="Opacity" Value="0.2"/>
</Core:DataTriggerBehavior>
<Core:DataTriggerBehavior
Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsEnabled}"
Value="True">
<Core:ChangePropertyAction PropertyName="Opacity" Value="1"/>
</Core:DataTriggerBehavior>
</Interactivity:Interaction.Behaviors>
</Path>
</Canvas>
</Button>
</Window.Resources>
<Grid>
<ContentControl Name="MyButton1" Content="{StaticResource myButtonConcentration}" />
<ContentControl Name="MyButton2" Content="{StaticResource myButtonConcentration}" />
</Grid>
