C# Custom Event Handler replicating textBox1_TextChanged event handler

[qwedster]

Howdy!

I want to write a Custom Event Handler replicating textBox1_TextChanged event handler to update textBox2 with textBox1 text as I type. I tried the following in vain. Please help.



The code snippet:

// CustomEventArgs.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace WindowsFormsApplication1
{
    delegate void CustomEventHandler(object sender, CustomEventArgs e);
 
    public class CustomEventArgs : EventArgs
    {
        string TextBoxText;
 
        public CustomEventArgs(string TextBoxText)
        {
            this.TextBoxText = TextBoxText;
        }
 
        internal string TextBoxTextChanged
        {
            get
            {
                return TextBoxText;
            }
        }
    }
}
 

// Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
 
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();          
        }
 
        private event CustomEventHandler TextBox1Event;
 
        private void TextBox1_CustomTextChanged(object sender, CustomEventArgs e)
        {
            textBox2.Text = e.TextBoxTextChanged;
        }
 
        private void OnTextBox1Event(CustomEventArgs e)
        {
            if (TextBox1Event != null)
            {
                TextBox1Event(this, e);
            }
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
            TextBox1Event += new CustomEventHandler(TextBox1_CustomTextChanged);
            CustomEventArgs TextBox1EventArgs = new CustomEventArgs(textBox1.Text);
            OnTextBox1Event(TextBox1EventArgs);
        }
   }
}
 

Thanks.

why not just update one from the other's textchanged event?
