Try something like:

<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presenta...
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml...
<StackPanel Orientation="Vertical">
<Slider x:Name="zoom" Minimum="0.5" Maximum="2" Value="1" Width="150"
HorizontalAlignment="Left"/>
<Grid>
<Grid.LayoutTransform>
<ScaleTransform ScaleX="{Binding ElementName=zoom, Path=Value}"
ScaleY="{Binding ElementName=zoom, Path=Value}" />
</Grid.LayoutTransform>
<Button Margin="50" HorizontalAlignment="Left" Content="Press Me"/>
</Grid>
</StackPanel>
</Page>
