Detect mouse location after Silverlight window loaded

I'm running a web page that has a SL 'box' in it.

I know how to use the MouseEnter and MouseLeave to detect if the mouse has entered the SL 开发者_StackOverflow社区box or left it.

My question is how to detect if the mouse is inside or outside the SL box when it has just loaded.

Thanks.

Here is a step-by-step post for building a Silverlight app that detects whether the mouse is over the Silverlight control when it is instantiated.

Step 1: Create a sample Silverlight application with Visual Studio (File / New Project / Silverlight Application)

Step 2: Edit the MainPage.xaml, and place the following code inside the UserControl's Grid:

<Grid HorizontalAlignment="Center" VerticalAlignment="Center">
    <TextBlock x:Name="x_Text" Text="Mouse Was Not Over" />
</Grid>

Step 3: Edit the MainPage.cs, and replace the MainPage class with the following code:

public partial class MainPage : UserControl
{
    public MainPage()
    {
        InitializeComponent();
        base.MouseEnter += OnMouseEnter;
        base.Loaded += OnLoaded;
    }

    void OnMouseEnter(object sender, MouseEventArgs e)
    {
        x_Text.Text = "Mouse Was Over";
        base.MouseEnter -= OnMouseEnter;
    }

    void OnLoaded(object sender, EventArgs e)
    {
        System.Windows.Threading.DispatcherTimer timer = new System.Windows.Threading.DispatcherTimer();
        timer.Interval = new TimeSpan(300 * TimeSpan.TicksPerMillisecond);
        timer.Tick += delegate(object senderTick, EventArgs eTick)
        {
            base.MouseEnter -= OnMouseEnter;
            timer.Stop();
        };
        timer.Start();
    }
}

Step 4: Build and Run! Try it with the mouse over the center of the Silverlight control and outside of the control to see the results!
