Have a look at this code, it might give you an idea of how to get started:

C#

public class UserControl : Control
{
   private TextBox textBox1;
   public UserControl()
   {
      textBox1 = new System.Windows.Forms.TextBox();
      textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(textBox1_KeyPress);
   }

   public delegate void CustomKeyPressEventHandler(object sender, System.Windows.Forms.KeyPressEventArgs e);

   public event CustomKeyPressEventHandler OnCustomKeyPress;

   private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
   {
      if (OnCustomKeyPress != null)
         OnCustomKeyPress(sender, e);
   }
}
