标签: c# wpf windows-phone-8 listbox windows-phone

我正在处理Windows Phone 8 application,我有列表框,里面有项目,对于我使用过DataTemplate的项目,现在我有一个样式,我已经将它应用于List作为ItemContainerStyle。

基本上就是这样,我有一个默认颜色为灰色的列表项目,现在当我点击该项目时,颜色灰色应该变为红色,以便它向用户表明他已经选择了该项目。 / p>

我的代码有效,但不适用于背景,而是应用为前景。

列表框:

<ListBox Name="listBox" 
         HorizontalAlignment="Stretch"
         ItemTemplate="{StaticResource DefaultTemplate}"
         ItemContainerStyle="{StaticResource ListBoxItemStyle}"/>

数据模板:

 <DataTemplate x:Key="DefaultTemplate">
            <Border  
                    Background="#e3e8f0"
                    Margin="0,2,0,0" 
                    VerticalAlignment="Stretch"
                    HorizontalAlignment="Stretch">
                <Grid       Width="Auto"
                            HorizontalAlignment="Center"
                            VerticalAlignment="Center">
                    <TextBlock
                                           Text="{Binding Path=Text}" 
                                           HorizontalAlignment="Center"
                                           Padding="10,25,10,25"
                                           TextWrapping="Wrap"
                                           MinHeight="80"
                                           VerticalAlignment="Center"
                                           TextAlignment="Center"
                                           Style="{StaticResource TextStyle}"
                                           Foreground="Black"/>
</Grid>
            </Border>
        </DataTemplate>

ListBoxItemStyle:

您不需要为此覆盖ControlTemplate。如果您想要更改列表框的高亮笔刷,则将ListBox放在ListBox资源下,覆盖ListBox的系统高亮笔刷。

<ListBox>
  <ListBox.Resources>
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                      Color="Red"/>
  </ListBox.Resources>
</ListBox>

更新:好的,既然您没有明确指出您使用的是Silverlight WPF框架的子集API,那么它的所有<Style x:Key="ListBoxItemStyle1" TargetType="ListBoxItem"> <Setter Property="Background" Value="Transparent"/> <Setter Property="BorderThickness" Value="0"/> <Setter Property="BorderBrush" Value="Transparent"/> <Setter Property="Padding" Value="0"/> <Setter Property="HorizontalContentAlignment" Value="Left"/> <Setter Property="VerticalContentAlignment" Value="Top"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <Border x:Name="LayoutRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"/> <VisualState x:Name="Disabled"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="LayoutRoot"> <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource TransparentBrush}"/> </ObjectAnimationUsingKeyFrames> <DoubleAnimation Duration="0" To=".5" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="ContentContainer"/> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="SelectionStates"> <VisualState x:Name="Unselected"/> <VisualState x:Name="Selected"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground" Duration="0"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <SolidColorBrush Color="White"/> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> <ObjectAnimationUsingKeyFrames Storyboard.TargetName="border" Storyboard.TargetProperty="Background" Duration="0"> <DiscreteObjectKeyFrame KeyTime="0"> <DiscreteObjectKeyFrame.Value> <SolidColorBrush Color="YellowGreen"/> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <StackPanel x:Name="border" Orientation="Horizontal"> <CheckBox x:Name="checkBox" IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IsSelected, Mode=TwoWay}" DataContext="{TemplateBinding IsSelected}" Visibility="{Binding Converter={StaticResource BooleanToVisibilityConverter}}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"/> <ContentControl x:Name="ContentContainer" ontentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/> </StackPanel> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> 都不一样。

对于Windows手机,你想做这样的事情

ListBox

然后设置<ListBox x:Name="databoundListBox" ItemContainerStyle="{StaticResource ListBoxItemStyle1}" SelectionMode="Multiple"/>

的样式
{{1}}
