How to change a path fill (on a button) with triggers in XAML

Question

I have a button with a path as icon,i want to change the fill of the path when the mouse is over the whole button (not only the path). Thanks.

You may bind Path.Fill to the Foreground property of the Button and modify the Foreground in a Button Style:

<Button Name="Test_Button" Width="220" Height="80" Padding="2">
    <Canvas Width="76" Height="76" Clip="F1 M 0,0L 76,0L 76,76L 0,76L 0,0">
        <Path Canvas.Left="19" Canvas.Top="19" Width="38" Height="38" Stretch="Fill"
              Fill="{Binding Foreground, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Button}}"
              Data="F1 M 35,19L 41,19L 41,35L 57,35L 57,41L 41,41L 41,57L 35,57L 35,41L 19,41L 19,35L 35,35L 35,19 Z">
        </Path>
    </Canvas>
    <Button.Style>
        <Style TargetType="Button">
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Foreground" Value="Red" />
                </Trigger>
                <Trigger Property="IsMouseOver" Value="False">
                    <Setter Property="Foreground" Value="Gray" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </Button.Style>
</Button>
