Question

我正在使用这个记忆游戏应用程序，试图学习WP7。想象一下屏幕上有6个独特的彩色按钮，用户必须重复这个按钮。

首先通过，禁用所有按钮，更改Button1的背景
启用所有按钮，用户点击按钮1，游戏继续......
第二次通过，禁用所有按钮，按钮1和3将突出显示
只更改Button3的背景（调试显示更改Button1背景的程序已运行）

按钮的突出显示只是变为较浅的背景。无论点击什么按钮，都无法更改次要传递中的背景颜色。

样式XAML：

<phone:PhoneApplicationPage.Resources>
        <Style x:Key="ButtonStyle1" TargetType="Button">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Grid Background="Transparent">
                            <VisualStateManager.VisualStateGroups>
                                <!--Define the states for the common states. The states in a

                                <VisualStateGroup x:Name="CommonStates">
                                    <!--Define the VisualStates in this VistualStateGroup.-->

                        </Grid>
                        <!--The parts of the button control will be defined here.-->

按钮：

<Button Height="121" HorizontalAlignment="Left" Margin="14,61,0,0" Name="but1" VerticalAlignment="Top" Width="197" Background="#FF7D0000" BorderBrush="Black" Foreground="Red" BorderThickness="0" Padding="0" Style="{StaticResource ButtonStyle1}" Click="but1_Click" />

我应该复制一个StackPanel / Rectangle来替换我的按钮吗？或者我缺少一种风格或基本的东西？

解决。

我改变了按钮风格的按下状态 - 这是在比较了我的风格和按钮的默认风格之后。我似乎错过了一些代码。

<VisualState x:Name="Pressed">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneBackgroundBrush}"/>
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/>
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground">
            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/>
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>
