Question

将XAML用于mettro应用程序我在按钮上遇到问题，每当鼠标悬停按钮变成隐藏时，

下面是按钮的代码：

<Button x:Name="btnLogin"
        Content="Login"
        Click="btnLogin_click"
        HorizontalAlignment="Left"
        Height="50"
        Margin="83,255,0,0"
        VerticalAlignment="Top"
        Width="114"
        Background="#FFE6410C" />

Answer 1

如果要删除悬停效果。您需要自定义按钮模板。下面是默认模板，我已经注释掉了PointerOver视觉状态。所以指针悬停时不会有任何变化。

<Button x:Name="btnLogin"
Content="Login"
Click="btnLogin_click"
HorizontalAlignment="Left"
Height="50"
Margin="83,255,0,0"
VerticalAlignment="Top"
Width="114"
Background="#FFE6410C" 
Style="{StaticResource MyButton}"/>


<Style TargetType="Button" x:Key="MyButton">
    <Setter Property="Background" Value="{StaticResource ButtonBackgroundThemeBrush}" />
    <Setter Property="Foreground" Value="{StaticResource ButtonForegroundThemeBrush}" />
    <Setter Property="BorderBrush" Value="{StaticResource ButtonBorderThemeBrush}" />
    <Setter Property="BorderThickness" Value="{StaticResource ButtonBorderThemeThickness}" />
    <Setter Property="Padding" Value="12,4,12,4" />
    <Setter Property="HorizontalAlignment" Value="Left" />
    <Setter Property="VerticalAlignment" Value="Center" />
    <Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}" />
    <Setter Property="FontWeight" Value="SemiBold" />
    <Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">

                            <VisualState x:Name="Normal" />
                            <VisualState x:Name="PointerOver">

这是可以帮助您的 XAML：

<Style x:Key="ButtonStyle1" TargetType="Button">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid Background="Transparent">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="Pressed"/>
                            <VisualState x:Name="MouseOver">
                                <Storyboard>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneBackgroundBrush}"/>
                                    </ObjectAnimationUsingKeyFrames>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/>
                                    </ObjectAnimationUsingKeyFrames>
                                    <ColorAnimation Duration="0" To="Cyan" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" Storyboard.TargetName="ButtonBackground" d:IsOptimized="True"/>
                                </Storyboard>
                            </VisualState>
                            <VisualState x:Name="Disabled">
                                <Storyboard>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/>
                                    </ObjectAnimationUsingKeyFrames>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/>
                                    </ObjectAnimationUsingKeyFrames>
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

尝试更改值。并且不要忘记将样式属性添加到按钮中。
