Question

I have a wppf button with a background image.

When I mouse over background will be empty and a button is shown.

How can I disable mouse effect?

<Button BorderBrush="{x:Null}" Content="Reset" BorderThickness="0"Foreground="White" Focusable="False">
                        <Button.Background>
                            <ImageBrush ImageSource="button.png" />
                        </Button.Background>

Here’s how I disable the visual mouseover effects on buttons. I left in some of my settings just to get you a feel of how to play with the triggers and stuff, feel free to experiment!

<Style TargetType="Button" x:Key="ImageButton" BasedOn="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">
    <Setter Property="FocusVisualStyle" Value="{x:Null}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border Name="border" 
                        BorderThickness="{TemplateBinding BorderThickness}"
                        Padding="{TemplateBinding Padding}" 
                        BorderBrush="{TemplateBinding BorderBrush}" 
                        CornerRadius="5"
                        Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="BorderBrush" Value="Gainsboro" />
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter Property="Opacity" Value="0.25" />
                        <Setter Property="BorderBrush" Value="Transparent" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

EDIT: Using the “BasedOn” + setting FocusVisualStyle to null (first 2 lines) gets rid of the mouse over effects. Everything else is just examples. I added a border there in order to play with it through a trigger (since I want a custom mouseover effect).
