WP8 get Grid (content panel) height in run time

I have a basic question. I have my MainPage.xaml code like this,

<!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel Grid.Row="0" Margin="12,17,0,28">

            <TextBlock Text="{Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}" 
                       Margin="9,-7,0,0"  Style="{StaticResource PhoneTextTitle1Style}" Foreground="Black" />
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0" >

        </Grid>
    </Grid>

In my MainPage.xaml.cs file,

public MainPage()
        {
            InitializeComponent();

            MessageBox.Show(ContentPanel.Height.ToString());
        }

My message box returns NaN value but I would like to get a specific value rather than indefinite value.

Thanks.

Based on the suggestions,

public MainPage()
        {
            InitializeComponent();

            this.Loaded += new RoutedEventHandler(DisplayMessage);
        }

void DisplayMessage(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(ContentPanel.ActualHeight.ToString());
        }

This returns me height of my content panel.

Thanks.

you should check the actual height of your content panel in the Loaded event. In the constructor it will be NaN because the actual values are not yet determined...
