помогите разобраться почему в методе private void button1_Click(object sender, System.EventArgs e)
показывается визуальное изменение StatusBar1 а в методе public void TestMetod() не показывается ?

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace WindowsApplication2
{
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
protected System.Windows.Forms.StatusBar statusBar1;
protected System.ComponentModel.Container components = null;

public Form1()
{
InitializeComponent();
}
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
protected void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.statusBar1 = new System.Windows.Forms.StatusBar();
this.SuspendLayout();
this.button1.Location = new System.Drawing.Point(72, 128);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(96, 24);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.Click += new System.EventHandler(this.button1_Click);
this.statusBar1.Location = new System.Drawing.Point(0, 251);
this.statusBar1.Name = "statusBar1";
this.statusBar1.Size = new System.Drawing.Size(292, 22);
this.statusBar1.TabIndex = 1;
this.statusBar1.Text = "statusBar1";
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(292, 273);
this.Controls.AddRange(new System.Windows.Forms.Control[] {
this.statusBar1,
this.button1});
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);

}
[STAThread]
static void Main()
{
Application.Run(new Form1());
}

private void button1_Click(object sender, System.EventArgs e)
{
//Здесь изменяется
for (int i=0;i<=10000;i++)statusBar1.Text = i.ToString();
Test qwe = new Test();
// а здесь нет
qwe.TestMetod();
}
}
public class Test:Form1{
public void TestMetod(){
for (int i=0;i<=10000;i++)statusBar1.Text = i.ToString();
}
}
}
