如何使wpf行缩小以适应内容

I have a grid with two rows plus a grid splitter. I want the top row's height to be as small as possible by default (in this case, the height of the button) The bottom row should expand to take up the remaining space in the grid. I want the grid splitter there to allow the user to change the size as needed.

我有一个有两行的网格和一个网格分割器。我希望默认情况下顶行的高度尽可能小(在这种情况下,按钮的高度)底部行应该展开以占据网格中的剩余空间。我希望那里的网格分割器允许用户根据需要改变大小。

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="5" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>

    <Button Grid.Row="0" Content="A little old button" VerticalAlignment="Center" />
    <GridSplitter Grid.Row="1" Background="Black" HorizontalAlignment="Stretch" />
    <TextBlock Grid.Row="2" TextWrapping="Wrap">
        Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem. Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum. Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.
    </TextBlock>
</Grid>
