Yksinkertainen C# testi

Hei,

Aloittelin tuota C#-ohjelmointia ja ihan ekana tein painikkeen ja tekstiruudun. Painiketta painamalla tekstiruutuun pitäisi tulostua tekstiä.

En kuitenkaan painiketta painamalla saa mitään tekstiä tulostumaan. Osaisiko joku viisas auttaa?

Koodini on seuraavanlainen:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace WindowsApplication2
{
   ///
   /// Summary description for Form1.
   ///
   public class Form1 : System.Windows.Forms.Form
   {
      private System.Windows.Forms.TextBox textBox1;
      private System.Windows.Forms.Button NaytaTeksti;
      ///
      /// Required designer variable.
      ///
      private System.ComponentModel.Container components = null;

      public Form1()
      {
         //
         // Required for Windows Form Designer support
         //
         InitializeComponent();

         //
         // TODO: Add any constructor code after InitializeComponent call
         //
      }

      private void NaytaTeksti_Click(object sender, EventArgs e)

      {

         textBox1.Text = "Homma toimii";

      }




      ///
      /// Clean up any resources being used.
      ///
      protected override void Dispose( bool disposing )
      {
         if( disposing )
         {
            if (components != null)
            {
               components.Dispose();
            }
         }
         base.Dispose( disposing );
      }

      #region Windows Form Designer generated code
      ///
      /// Required method for Designer support - do not modify
      /// the contents of this method with the code editor.
      ///
      private void InitializeComponent()
      {
         this.NaytaTeksti = new System.Windows.Forms.Button();
         this.textBox1 = new System.Windows.Forms.TextBox();
         this.SuspendLayout();
         //

         this.NaytaTeksti.Name = "NaytaTeksti";
         this.NaytaTeksti.Size = new System.Drawing.Size(136, 23);
         this.NaytaTeksti.TabIndex = 0;
         this.NaytaTeksti.Text = "Nayta";

         this.textBox1.Text = "textBox1";

         this.ClientSize = new System.Drawing.Size(292, 273);

         this.Controls.Add(this.NaytaTeksti);
         this.Name = "Form1";
         this.Text = "Form1";
         this.ResumeLayout(false);

      }
      #endregion
