我的页面上有一个按钮,上面有这个XAML:
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom"
Width="50" Height="50" HorizontalContentAlignment="Left"
BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="50,0,0,0">
<Button.Style>
<Style TargetType="Button">
<Setter Property="Background" Value="Green"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
但是当我把鼠标放在按钮上时,按钮的背景变成了默认的窗口灰色背景。
有什么问题吗?
这是鼠标悬停前后的按钮图片:

要删除Button
上的默认MouseOver
行为,您需要修改ControlTemplate
。将您的Style
定义更改为以下内容应该可以解决此问题:
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="Green"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" BorderBrush="Black" BorderThickness="1">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
编辑:虽然晚了几年,但实际上你可以在边框内设置边框画笔。如果有人指出了这一点,但它看起来不像是...

一个稍微困难一点的答案,使用ControlTemplate并具有动画效果(改编自https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/customizing-the-appearance-of-an-existing-control)
在资源字典中,为按钮定义一个控件模板,如下所示:
<ControlTemplate TargetType="Button" x:Key="testButtonTemplate2">
<Border Name="RootElement">
<Border.Background>
<SolidColorBrush x:Name="BorderBrush" Color="Black"/>
</Border.Background>
<Grid Margin="4" >
<Grid.Background>
<SolidColorBrush x:Name="ButtonBackground" Color="Aquamarine"/>
</Grid.Background>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="4,5,4,4"/>
</Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Border>
</ControlTemplate>
在XAML中,您可以为按钮使用上面的模板,如下所示:
定义你的按钮
<Button Template="{StaticResource testButtonTemplate2}"
HorizontalAlignment="Center" VerticalAlignment="Center"
Foreground="White">My button</Button>

用于更改按钮样式
第一步:定义资源样式
<Window.Resources>
<Style x:Key="OvergroundIn" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="#FF16832F">
<ContentPresenter TextBlock.Foreground="White" TextBlock.TextAlignment="Center" Margin="0,8,0,0" ></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="#FF06731F">
<ContentPresenter TextBlock.Foreground="White" TextBlock.TextAlignment="Center" Margin="0,8,0,0" ></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
<Style x:Key="OvergroundOut" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="#FFF35E5E">
<ContentPresenter TextBlock.Foreground="White" TextBlock.TextAlignment="Center" Margin="0,8,0,0" ></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="#FFE34E4E">
<ContentPresenter TextBlock.Foreground="White" TextBlock.TextAlignment="Center" Margin="0,8,0,0" ></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
第二个定义按钮代码
<Border Grid.Column="2" BorderBrush="LightGray" BorderThickness="2" CornerRadius="3" Margin="2,2,2,2" >
<Button Name="btnFichar" BorderThickness="0" Click="BtnFichar_Click">
<Button.Content>
<Grid>
<TextBlock Margin="0,7,0,7" TextAlignment="Center">Fichar</TextBlock>
</Grid>
</Button.Content>
</Button>
</Border>
第3个代码
public void ShowStatus()
{
switch (((MainDto)this.DataContext).State)
{
case State.IN:
this.btnFichar.BorderBrush = new SolidColorBrush(Color.FromRgb(243, 94, 94));
this.btnFichar.Style = Resources["OvergroundIn"] as Style;
this.btnFichar.Content = "Fichar Salida";
break;
case State.OUT:
this.btnFichar.BorderBrush = new SolidColorBrush(Color.FromRgb(76, 106, 83));
this.btnFichar.Style = Resources["OvergroundOut"] as Style;
this.btnFichar.Content = "Fichar Entrada";
break;
}
}
