How to make a GroupBox size to its content

Question

Very simple request. How do I make (or can I make) a GroupBox size to its content.

I have a groupbox which contains a number of items in a stackpanel. If I add a value then the GroupBox will not show the value. I have tried with height and width set to Auto but that does not work.

Check an example:

<GroupBox Margin="10,10,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Padding="10">
    <StackPanel>
        <CheckBox x:Name="checkBox1" Content="CheckBox1" />
        <CheckBox x:Name="checkBox2" Content="CheckBox2" />
        <CheckBox x:Name="checkBox3" Content="CheckBox3" />
    </StackPanel>
</GroupBox>
