Vista - Sizing a FlowDocumentPageViewer in XAML

Greetings,

I have a Window defined roughly as a Grid with a couple of controls
and a Stackpanel. The Stackpanel occupies the bottom third of the
Grid. The second component within the Stackpanel is a
FlowDocumentPageViewer. I'd like the height of the
FlowDocumentPageViewer to automatically fill the bottom part of the
Stackpanel and therefore the bottom part of the main Window as well.
Unfortunately the behavior I see is the FlowDocumentPageViewer
extending well below the viewable part of the Window, hiding the
controls that allow the user to scroll from page to page. I can hard-
code the height easily enough (I use 200 in my code snippet below),
but that defeats the point of having a Stackpanel and doesn't allow
for resizing, etc.

Is there a way to have the FlowDocumentPageViewer automatically resize
to fit the remainder (i.e. bottom portion) of the stackpanel? My guess
is that there is some markup extension somewhere that fits the bill,
but finding it eludes me.

Following is the window definition, without the details:

<Window x:Class=...>
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Canvas Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2"
Grid.RowSpan="2">
<MyControl:ctrlMyControl x:Name="m_ctrlClassicalWave"
Canvas.ZIndex="100" Canvas.Top="90" Canvas.Left="100"/>
<Image Canvas.Top="50" Canvas.Left="50">
...
</Image>
<Ellipse Canvas.Top="50" Canvas.Right="100" Width="30"
Height="100">
...
</Ellipse>
</Canvas>
<StackPanel Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2">
<RichTextBox Height="18" Width="100">
...
</RichTextBox>
<FlowDocumentPageViewer Height="200">
<FlowDocument>
<Paragraph>
A bunch of paragraphs and text here that goes on for
several pages....
</Paragraph>
</FlowDocument>
</FlowDocumentPageViewer>
</StackPanel>
</Grid>
</Window>

Thanks in advance!!

You could use a DockPanel, or try HorizonalAlignment=Stretch &
VerticalAlignment=Stretch.
