Question

我制作的风格让TextBlock看起来像一个链接：

<Style x:Key="linkStyle" TargetType="TextBlock">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="TextDecorations" Value="Underline" />
        </Trigger>
    </Style.Triggers>
    <Setter Property="Cursor" Value="Hand" />
    <Setter Property="Foreground" Value="Blue" />
    <EventSetter Event="MouseLeftButtonDown" Handler="navigateLink" />
</Style>

仅当TextBlock.Text以 http：// 开头时如何应用？

试试这个

<Style x:Key="linkStyleConditional" TargetType="{x:Type TextBlock}">
    <Style.Triggers>
        <MultiDataTrigger>
            <MultiDataTrigger.Conditions>
                <Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsMouseOver}" Value="True"/>
                <Condition Binding="{Binding Path=Text, Converter={StaticResource SomeConverter}}" Value="True"/>
            </MultiDataTrigger.Conditions>
            <Setter Property="Foreground" Value="Orange" />
        </MultiDataTrigger>
    </Style.Triggers>
</Style>

在SomeConverter中写入逻辑，如果文本以http //开头，则返回true，否则返回false。我希望这会有所帮助。
