改用"运行"文本块

    <TextBlock TextWrapping="Wrap">
        <Hyperlink Command="{Binding Path=Source1}">
            <Run>
                <Run.Style>
                    <Style TargetType="Run">
                        <Style.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Text"  Value="My mouse is over" />
                            </Trigger> 
                        </Style.Triggers>
                        <Setter Property="Text"  Value="Click here to set Source1" />
                    </Style>
                </Run.Style>
            </Run>
        </Hyperlink>
    </TextBlock>
