WPF中的条件样式

Question

我做了一个TextBlock看起来像链接的风格:

<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>

如何在TextBlock.Text以http://开头时应用它？

Answer 1

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.我希望这将有所帮助.
