刪除Windows Phone的8 C＃

Question

上按一下按鈕標準藍色背景我使用下面的代碼顯示了許多按鈕在我的滾動型

foreach (RingModel ring in app.rings) 
      { 
       Button btn = new Button(); 
       btn.BorderThickness = new Thickness(0, 0, 0, 0); 

       Image img = new Image(); 
       img.Width = 100; 
       img.Height = 100; 
       img.Margin = new Thickness(5, 0, 0, 0); 

       Uri myUri = new Uri(ring.ringThumbNailImagePath, UriKind.Absolute); 
       BitmapImage bmi = new BitmapImage(); 
       bmi.CreateOptions = BitmapCreateOptions.None; 
       bmi.UriSource = myUri; 
       img.Source = bmi; 
       btn.Content = img; 
       btn.Tag = i; 
       btn.Click += Ring_Click; 

       scrollStackPanel.Children.Add(btn); 
       i++; 
      } 

然而這些按鈕是給上點擊藍色的背景。我想讓它透明。我怎樣才能使它成爲可能。

對您分享的App.xaml的<Application.Resources>

寫這個

<SolidColorBrush x:Key="ButtonDisabledBackgroundThemeBrush" Color="Ur color"/> 
    <SolidColorBrush x:Key="ButtonPressedBackgroundThemeBrush" Color="Ur Color" />

使用自定義樣式：

<Style x:Key="ButtonStyle1" TargetType="ButtonBase"> 
    <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 PhoneFontSizeMedium}"/> 
    <Setter Property="Padding" Value="10,5,10,6"/> 

    <Setter Property="Template"> 
    <Setter.Value> 
     <ControlTemplate TargetType="ButtonBase"> 
     <Grid Background="Transparent"> 
      <VisualStateManager.VisualStateGroups> 
      <VisualStateGroup x:Name="CommonStates"> 
       <VisualState x:Name="Normal"/> 
       <VisualState x:Name="MouseOver"/> 
       <VisualState x:Name="Pressed"> 
       <Storyboard> 
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground"> 
        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneButtonBasePressedForegroundBrush}" /> 
        </ObjectAnimationUsingKeyFrames> 
       </Storyboard> 
       </VisualState> 
       <VisualState x:Name="Disabled"> 
       <Storyboard> 
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground"> 
        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}" /> 
        </ObjectAnimationUsingKeyFrames> 
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="BorderBrush"> 
        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}" /> 
        </ObjectAnimationUsingKeyFrames> 
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Background"> 
        <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent" /> 
        </ObjectAnimationUsingKeyFrames> 
       </Storyboard> 
       </VisualState> 
      </VisualStateGroup> 
      </VisualStateManager.VisualStateGroups> 
      <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0" Background="{TemplateBinding Background}" Margin="{StaticResource PhoneTouchTargetOverhang}" > 
      <ContentControl x:Name="ContentContainer" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}" Padding="{TemplateBinding Padding}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/> 
      </Border> 
     </Grid> 
     </ControlTemplate> 
    </Setter.Value> 
    </Setter> 
</Style> 

然後分配樣式的按鈕：

btn.Style = (Style) Resources["ButtonStyle1"];
