在silverlight中按下按钮突出显示

我有一个按钮,我添加一个图像作为其背景,但当我按下按钮时,我在按钮的背景上得到一个正方形(突出显示).我怎么能删除这个？

<Button VerticalAlignment="Top" HorizontalAlignment="Left" BorderBrush="Transparent" Click="FirstCubeSelected" x:Name="cube1Button"   Padding="0"   Margin="1,-1,0">
                <Image x:Name="buttonImage" Source="/images/cub2onbtn.png" Width="176" Height="176" />
            </Button>

我通常在表达式混合中执行此操作,但我现在无法访问它

解决方法

您需要从按钮中删除按下的视觉样式：

<Style x:Key="ButtonStyle1" targettype="Button">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
        <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
        <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
        <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
        <Setter Property="Padding" Value="10,3,10,5"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate targettype="Button">
                    <Grid Background="Transparent">
                        <visualstatemanager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="normal"/>
                                <VisualState x:Name="MouSEOver"/>
                                <VisualState x:Name="pressed"/>
                                <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>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground">
                                            <discreteObjectKeyFrame KeyTime="0" Value="Transparent"/>
                                        </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </visualstatemanager.VisualStateGroups>
                        <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="{StaticResource PhonetouchTargetoverhang}">
                            <ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
