WPF Context menus and "scope"

I've recently started looking into WPF. What is the expected scope of a
context menu? For example, I have a web browser application. To the
main "Page" I added a context menu (along with various other children
embedded within a Grid - buttons, etc).
If I then launch the application and right click on an empty part of the
page, I do NOT get a context menu. If I right click on any of the
children, say a Button, the context menu appears.

What I EXPECTED to happen was the context menu to appear when I right
clicked on an empty part of the page. I did NOT expect it to "cascade"
down to children. I only very briefly tried this and am about to go
home for the day. I'll poke into it in more depth tomorrow, just
wanted to see if this immediately jumped out at anyone as obvious.

Thanks,
Adam

OK, it appears I was not going crazy yesterday, but the context menu is
working exactly opposite of how I would expect. I created a basic
simple WPF application (not a browser application as in my attempt
yesterday). The XAML looks is simply:

<Window x:Class="WpfContextMenuTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
<Grid.ContextMenu>
<ContextMenu>
<MenuItem Header="Test Item" />
</ContextMenu>
</Grid.ContextMenu>
<Button Height="23" HorizontalAlignment="Left"
Margin="44,42,0,0" Name="button1" VerticalAlignment="Top"
Width="75">Button</Button>
</Grid>
</Window>


When I run that, if I right click on the form itself, I get no context
menu. If I right click on the button, I get my "Test Item" context
menu. I want the inverse of that. The button shouldn't have a context
menu, and when I click on the "background", that should popup the
menu. What am I doing wrong here??

Thanks,
Adam
