    Hello,

    how I can or what is the value definition. mainly if I want to jump to line 12 which value I should use

    Because Label do not have method to get the lines, we can do this by using Label's fontSize and add default padding (10) to get the text line height, then multiply by 12 like following code.

    MyScrollVIew.ScrollToAsync(0, (MyLabel.FontSize+10)*12, false);
    

    My XAML layout like following.

    <ScrollView x:Name="MyScrollVIew" HeightRequest="100">
                <Label x:Name="MyLabel"  FontSize="Title"></Label>
    </ScrollView>
    

    Best Regards,

    Leon Lu
