How can I change the default button highlight in WPF C#

So I have this button:

enter image description here

And I need to remove that blue rectangle. I tried to add the following event triggers (IsMouseOver and IsFocused), and set the background transparent:

    <Style x:Key="ButtonStyle" TargetType="Button">

        <Setter Property="FocusVisualStyle" Value="{x:Null}" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="Border" Padding="0" SnapsToDevicePixels="true">
                        <ContentPresenter />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter TargetName="Border" Property="Background" Value="Transparent"/>
                        </Trigger>
                        <Trigger Property="IsFocused" Value="True">
                            <Setter TargetName="Border" Property="Background" Value="Transparent" />
                            <Setter Property="Background" Value="Transparent" />

                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

The button is inside this menu:

   <Menu HorizontalAlignment="Left" Height="40" Margin="0,80,0,0" VerticalAlignment="Top" Width="700" Background="WhiteSmoke">
        <Button x:Name="OrderBy" Content="Order By" Width="75" Margin="0,8,0,0"  Style="{DynamicResource ButtonStyle}"/>
        <GridSplitter Height="20" Width="1" Background="Black" Margin="0,8,0,0"/>
        <Button x:Name="Refresh" Content="Refresh" Width="75" Margin="0,8,0,0"/>
        <TextBox x:Name="Search" Height="23" TextWrapping="Wrap" Text="Search" Width="240"  Margin="250,8,0,0" HorizontalAlignment="Right"/>
    </Menu>

I am new to WPF and I already searched a lot to try to find an answer to this. Thank you for the help!

You have to rewrite a ControlTemplate for MenuItem, namely TopLevelItemTemplate and set in Trigger for IsHighlighted Border's Background to transparent. The highlighting comes from MenuItem not from Button. Try to put this to Resources of your Menu:

        <LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientBrush.GradientStops>
                <GradientStopCollection>
                    <GradientStop Color="#FFF" Offset="0.0"/>
                    <GradientStop Color="#CCC" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>

        <LinearGradientBrush x:Key="HorizontalNormalBrush" StartPoint="0,0" EndPoint="1,0">
            <GradientBrush.GradientStops>
                <GradientStopCollection>
                    <GradientStop Color="#FFF" Offset="0.0"/>
                    <GradientStop Color="#CCC" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>

        <LinearGradientBrush x:Key="LightBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientBrush.GradientStops>
                <GradientStopCollection>
                    <GradientStop Color="#FFF" Offset="0.0"/>
                    <GradientStop Color="#EEE" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>

        <LinearGradientBrush x:Key="HorizontalLightBrush" StartPoint="0,0" EndPoint="1,0">
            <GradientBrush.GradientStops>

                </GradientStopCollection>

                    <GradientStop Color="#AAA" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>

        <LinearGradientBrush x:Key="PressedBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientBrush.GradientStops>
                <GradientStopCollection>

                    <GradientStop Color="#FFF" Offset="1.0"/>
