Disable automatic MouseHover in Windows Presentation Foundation WPF C#

Question

I have created a Windows Presentation Foundation WPF application.

The problem is automatic MouseHover that creates blue shinning when I hover over a button.

I have checked all of the components, stackpanel, grid, button ... etc, and in my options there is no MouseHover action, it's somehow default hover and I cannot disable it. Can I somehow disable or change it?

This seems to be a wpf project, rather than Winforms. Or host a wpf control in Windows Forms? — 大陸北方網友, Jul 14 '20 at 09:03
if this is a wpf project have a look at the following link https://stackoverflow.com/questions/3854317/how-to-remove-default-mouse-over-effect-on-wpf-buttons — Joeri E, Jul 14 '20 at 09:06
Aight so if it's WPF project, then what can I do to change this automatic hover? — Simonsoft177, Jul 14 '20 at 09:08

You'd have to define a Style with a Template for your Button, where you then define the behaviour for certain Triggers. The Trigger you are looking for is called IsMouseOver. Here a little example, where the Background colour is set to Aqua.

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border
                    Width="{TemplateBinding Width}"
                    Height="{TemplateBinding Height}"
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}"
                    CornerRadius="0"
                    SnapsToDevicePixels="True">
                    <ContentPresenter 
                        Margin="{TemplateBinding Padding}"/>
                </Border>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <!-- Define your MouseOver behaviour here! E.g.:-->
                        <Setter Property="Background" Value="Aqua" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

I cant work it out. I dont have action isMouseOver, only MouseEnter, MouseDown, MouseLeave — Simonsoft177, Jul 14 '20 at 11:07
You are looking at the `Events ` and not the `Triggers`. As I said, you have to add a `Template ` to your style, which includes Triggers. — Florian H., Jul 14 '20 at 11:22
is it possible to shorten this code? Do I need to do all of these things in order to create a hover effect? Because right now i've got a this automatic hover and all I want is to change the color of it — Simonsoft177, Aug 07 '20 at 08:07
You usually bundle styles into a (or multiple) style class(es). This means you can reuse them. If you do not always want to change the `IsMouseOver` behaviour, you can create a base style and then create further styles that are based on that base style. — Florian H., Aug 10 '20 at 05:55
I got this working thants bro, but had to use diffrent code because this made my button flat and not dynamic. Still thank you — Simonsoft177, Aug 10 '20 at 08:27
