How do you disable MouseOver effects on a Button in WPF?
提问by jarmond
I'm trying to disable the MouseOver effect on buttons, or at least change the colour of it, in WPF.
我正在尝试在 WPF 中禁用按钮上的 MouseOver 效果，或者至少更改它的颜色。
I'm using the following style:
我正在使用以下样式：
<Style x:Key="Borderless" TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Button Background="{TemplateBinding Control.Background}"
Focusable="False">
<ContentPresenter
Margin="{TemplateBinding Control.Padding}"
HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}"
ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
RecognizesAccessKey="True"
Content="{TemplateBinding ContentControl.Content}" />
</Button>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
in Window.Resources, which I thought would override all the default behaviours. But it doesn't.
在 Window.Resources 中，我认为它会覆盖所有默认行为。但事实并非如此。
Any suggestions?
有什么建议？

Look what your control template boils down to:
看看你的控制模板归结为：
<ControlTemplate TargetType="{x:Type Button}">
<Button>
<ContentPresenter/>
</Button>
</ControlTemplate>
You're saying, "I want to replace the look of my button with... a button." The usage of the ControlTemplateis to replace the visual tree of a control. So you are replacing the visual tree of the existing button with another button. If you want to start a button from scratch, try using the SimpleStyles button:
你是说，“我想用……一个 button替换我的按钮的外观。” 的用法ControlTemplate是替换控件的可视化树。因此，您正在用另一个按钮替换现有按钮的可视化树。如果您想从头开始一个按钮，请尝试使用 SimpleStyles 按钮：
<Style TargetType="{x:Type Button}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border" CornerRadius="2" BorderThickness="1"
Background="#C0C0C0"
BorderBrush="#404040">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsDefaulted" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#808080" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#E0E0E0" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#606060" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border"
Property="Background" Value="#EEEEEE" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#AAAAAA" />
<Setter Property="Foreground" Value="#888888"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Notice that this template creates a button the simplest possible way: a border that contains the button content. It does not use another button embedded inside the template.
请注意，此模板以最简单的方式创建了一个按钮：一个包含按钮内容的边框。它不使用嵌入在模板中的另一个按钮。
