删除Windows Phone的8 C＃

Question

上按一下按钮标准蓝色背景我使用下面的代码显示了许多按钮在我的滚动型

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++; 
      } 

然而这些按钮是给上点击蓝色的背景。我想让它透明。我怎样才能使它成为可能。

对您分享的App.xaml的<Application.Resources>

写这个

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

使用自定义样式：

<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> 

然后分配样式的按钮：

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