WP7-單擊按鈕后無法設置背景

[英]WP7 - Cannot set background of button once it has been clicked

我正在使用此記憶游戲應用程序,嘗試學習WP7。 想象一下屏幕上有6個顏色獨特的按鈕,用戶必須重復該序列。

  1. 第一次通過,禁用所有按鈕,更改Button1的背景
  2. 啟用所有按鈕,用戶單擊按鈕1,游戲繼續...
  3. 第二次通過,禁用所有按鈕,按鈕1和3將突出顯示
  4. 僅更改Button3的背景(調試顯示已運行更改Button1的背景的過程)

按鈕的突出顯示只是更改為較淺的背景。 無論單擊什么按鈕,在隨后的傳遞中都無法更改背景顏色。

樣式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 are mutually exclusive to each other.-->
                                <VisualStateGroup x:Name="CommonStates">
                                    <!--Define the VisualStates in this VistualStateGroup.-->
                                    <VisualState x:Name="Normal"/>
                                    <VisualState x:Name="MouseOver" />
                                    <VisualState x:Name="Pressed">
                                        <Storyboard>
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
                                                <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneBackgroundBrush}"/>
                                            </ObjectAnimationUsingKeyFrames>

                                                <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneForegroundBrush}"/>
                                            </ObjectAnimationUsingKeyFrames>
                                            <ColorAnimation Duration="0" To="White" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" Storyboard.TargetName="ButtonBackground" d:IsOptimized="True"/>

                                    </VisualState>
                                    <VisualState x:Name="Disabled">
                                        <Storyboard>
                                            <DoubleAnimation Duration="0" Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Opacity" To="1"/>
                                        </Storyboard>
                                    </VisualState>
                                    </VisualStateGroup>
                                <!--Define the states for the focus states. The states in a

                                <VisualStateGroup x:Name="FocusStates">
                                    <!--Define the VisualStates in this VistualStateGroup.-->
                                    <VisualState x:Name="Focused" />
                                    <VisualState x:Name="Unfocused" />
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                            <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0" Margin="{StaticResource PhoneTouchTargetOverhang}" Background="{TemplateBinding Background}">
                                <ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                            </Border>
                        </Grid>
                        <!--The parts of the button control will be defined here.-->
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </phone:PhoneApplicationPage.Resources>

按鍵:

<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" />

我應該復制一個StackPanel / Rectangle來替換我的按鈕嗎? 還是我缺少一種風格或基本的東西?

解決了。

在比較了我的樣式和按鈕的默認樣式之后,我更改了按鈕樣式的“已按下”狀態。 似乎我缺少一些代碼。

<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>

這是黑暗中的刺傷:)
