WPF / XAML - 在ListBoxItem内部拉伸超链接

Question

我想拉伸黄色文本块以填充整个列。换句话说，我想用黄色覆盖蓝色，以使超链接从左到右可点击。请指教。

谢谢。

使用Button并定义自定义ControlTemplate，使其看起来像超链接：

<ListBox.ItemTemplate>
    <DataTemplate>
        <Button CommandParameter="{Binding ElementName=txtBlock}" Command="{Binding DataContext.DisplayFile, ElementName=AppMainWindow}" Cursor="Hand">
            <Button.Template>
                <ControlTemplate TargetType="Button">
                    <TextBlock x:Name="tb" Text="{Binding}" />
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="tb" Property="Foreground" Value="blue" />
                            <Setter TargetName="tb" Property="TextDecorations" Value="Underline" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Button.Template>
        </Button>
    </DataTemplate>
</ListBox.ItemTemplate>
