如何在WPF中的Button上禁用MouseOver效果？

Question

我试图在WPF中禁用按钮上的MouseOver效果,或者至少更改它的颜色.

我使用以下样式:

<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>

在Window.Resources中,我认为会覆盖所有默认行为.但事实并非如此.

有什么建议？

看看你的控制模板归结为:

<ControlTemplate TargetType="{x:Type Button}">
   <Button>
      <ContentPresenter/>
   </Button>
</ControlTemplate>

你说,"我想用...... 按钮取代我的按钮外观." 用法ControlTemplate是替换控件的可视树.因此,您要用另一个按钮替换现有按钮的可视树.如果要从头开始按钮,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>

请注意,此模板以最简单的方式创建按钮:包含按钮内容的边框.它不使用嵌入模板内的其他按钮.
