如何在Viewbox中拉伸Grid

Question

我想在Grid内展开Viewbox。我有上帝的代码不能正常工作。任何线索？

 <Viewbox HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
         <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"></RowDefinition>
                <RowDefinition Height="Auto"></RowDefinition>
            </Grid.RowDefinitions>
 </Grid>
</Viewbox>
