Vista - Simple Question re: Text in UserControl?

All:

I have created a simple custom control (UserControl derivative). When
the control is displayed, I would like it to display some text. What do
I add to the XAML below (C# code is fine as well) to have the control
display some static text? This seems like it should be a no-brainer,
but...

<UserControl x:Class="JeopardyControl.GamePanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<Rectangle x:Name="JeopardySquare"
Canvas.Top="0" Canvas.Left="0" VerticalAlignment="Stretch"
HorizontalAlignment="Stretch"
Margin="5" RadiusX="10" RadiusY="10" TextElement.Foreground="White">
<Rectangle.Fill>
<LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
<LinearGradientBrush.GradientStops>
<GradientStop Color="#0000ff" Offset="0" />
<GradientStop Color="#000088" Offset="1" />
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
</UserControl>

Thanks,

PS. When I tried this.AddText("xxx"), I got the following exception:
Content of a ContentControl must be a single element

But this single element can be a panel, which in turn can contain
multiple elements.

Choose a panel (StackPanel, WrapPanel, Canvas, Grid, etc...) and make it
your control's only child. The type you choose depends on the features
you want, each panel has different placements options. The simplest is
StackPanel, where each element is simply added after the other
vertically or horizontally. Grids are perfect for build columns/rows
oriented layouts. In Canvas, you can place your elements with X/Y
measurements. WrapPanels are like StackPanels, but the elements get
wrapped when the panel is resized. etc...

Then, place your elements inside the panel. For simple text, you may
want to use a Label or a TextBlock control. Check the documentation to
see what they can do.
