Question

我有ListBox和ListBoxItem的样式

<Style TargetType="{x:Type ListBox}">
        <Setter Property="Background" Value="{StaticResource DarkBackground}"/>
    </Style>
    <Style TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="{StaticResource LightBackground}"/>
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Margin" Value="5,0,5,0"/>
        <Setter Property="Padding" Value="5,0,5,0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListBoxItem}">
                    <Border Background="{TemplateBinding Background}" Height="35"
                                            BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                        <ItemsControl Focusable="False" Margin="{TemplateBinding Padding}" Foreground="{TemplateBinding Foreground}" VerticalContentAlignment="Center">
                            <ContentPresenter Tag="{Binding Path=Tag, RelativeSource={RelativeSource TemplatedParent}}" Content="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}"/>
                        </ItemsControl>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsSelected" Value="True">
                            <Setter Property="Background" Value="{StaticResource GlassFX}"/>
                            <Setter Property="BorderBrush" Value="White"/>
                            <Setter Property="BorderThickness" Value="1"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

我在MainWindow上添加了一个新的ListBox：

<ListBox ItemsSource="{Binding AvailableClient}">
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <ListBoxItem Tag="{Binding Path=ID}" Content="{Binding Path=Name}"/>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>

但我的约束不起作用......

如果改变风格

<ContentPresenter Tag="{Binding Path=Tag.ID, RelativeSource={RelativeSource TemplatedParent}}" Content="{Binding Path=Content.Name, RelativeSource={RelativeSource TemplatedParent}}"/>

所有工作。但我需要一个适用于许多列表框的通用样式。我怎么能这样做？

如果您正在使用VisualStudio在解决方案中创建新的Resource Dictionary，请将您的样式复制到其中：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style TargetType="{x:Type ListBox}">
        -Your style code here-
    </Style>
</ResourceDictionary>

然后，在您的Window / Usercontrol资源或最好是您的App.xaml文件中，加载您的资源字典，如下所示：

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="whatever you named the file.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

现在，您的自定义样式应覆盖解决方案中所有列表框的样式。如果您想在另一个解决方案中使用您的样式，只需将您创建的xaml文件放入解决方案中并像上面一样加载它。

带有syle和Datatemplate的ListBox
