WPF Button Content Multi-line

[MikeB]

I have a button template. I want the button text to be multiline, but I have no idea how to set this.

I know I can set this in the xaml where I create the button by adding a text block and using <LineBreak/> but this overrides the TextBlock used by the button template.

E.G: The following would work, but the text block defined replaces the text block used by the template. This is no good.

<Button Template="{StaticResource MenuButtonTemplate}">
     <TextBlock>
          Project<LineBreak/>Management
     </TextBlock>
</Button>

E.G: The following is my button template:

  <ControlTemplate x:Key="MenuButtonTemplate" TargetType="{x:Type Button}">
        <Border Name="MenuButtonBorder" 
                BorderBrush="Black" 
                BorderThickness="1"
                CornerRadius="3"
                Background="Transparent"
                TextBlock.Foreground="White"
                TextBlock.FontSize="12"
                TextBlock.TextAlignment="Center"
                Width="80"
                Margin="3,3,3,3">
            <Grid>
                <Rectangle Name="MenuButtonFocusCue" 
                           Visibility="Hidden"
                           Stroke="LightSteelBlue"
                           StrokeThickness="1"
                           SnapsToDevicePixels="True">
                </Rectangle>
                <ContentPresenter RecognizesAccessKey="True"
                                  Margin="2,2,2,2"
                                  VerticalAlignment="Center">
                </ContentPresenter>
            </Grid>
        </Border>
        <ControlTemplate.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter TargetName="MenuButtonBorder"
                        Property="Background"
                        Value="Transparent"/>
                <Setter TargetName="MenuButtonBorder"
                        Property="TextBlock.Foreground"
                        Value="Yellow"/>
            </Trigger>
            <Trigger Property="IsPressed" Value="True">
                <Setter TargetName="MenuButtonBorder"
                        Property="Background"
                        Value="Transparent"/>
                <Setter TargetName="MenuButtonBorder"
                        Property="TextBlock.Foreground"
                        Value="Yellow"/>
            </Trigger>
            <Trigger Property="IsKeyboardFocused" Value="True">
                <Setter TargetName="MenuButtonFocusCue" 
                        Property="Visibility"
                        Value="Visible"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>

Any suggestions would be appreciated.
