You shouldn't set the height properties when working with a ScrollViewer. If you strip it down to just the following and it still doesn't work, then it is something else in your project that is preventing it to work.

<ScrollViewer>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>
        <TextBlock Text="Hello" FontSize="320" />
        <TextBlock Grid.Row="1" Text="World" FontSize="320" />
    </Grid>
</ScrollViewer>
