I have been looking into event handling with C# and Silverlight and I can't seem to grasp it. I'm simply trying to get this adding event handlers in managed code example to compile from

I keep getting the errors "The name 'TextBlock_MouseEnter' does not exist in the current context.
"The name 'TextBlock_MouseLeave' does not exist in the current context.

Please help! Thanks in advance.

<UserControl x:Class="EventHandlingInSilverLight.MainPage"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="Layoutroot" Loaded="LayoutRoot_Loaded">
        <TextBlock Name="textBlock1"> Put the mouse over this text</TextBlock>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace EventHandlingInSilverLight
    public partial class MainPage : UserControl
        public MainPage()

        void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
            textBlock1.MouseEnter += new MouseEventHandler(textBlock1_MouseEnter);
            textBlock1.MouseLeave += new MouseEventHandler(textBlock1_MouseLeave);


In line 24 of your second code block you are adding the event handler 'textBlock1_MouseEnter' to the MouseEnter event, but you don't actually have a method defined with that name anywhere that I can see, thus the error you are getting. Create the methods.
