[Solved] text on progressbar in c# [closed]

This works – although I’d set the thread-sleep to more than 200 ms. Your problem was that you did the work in the UI thread and this way it never gets updated. For better visibility, just change the font color:

 private void Form1_Load(object sender, EventArgs e)
{
  Task t = new Task(() => StartUpdate());
  t.Start();

  t.ContinueWith(task => Console.WriteLine("Done loading"));
}

 private void StartUpdate()
{
  for (int i = 1; i <= 100; i++)
  {
    UpdateProgressBar(i);
  }
}

private void UpdateProgressBar(int i)
{
  if (progressBar1.InvokeRequired)
  {
    progressBar1.Invoke(new Action<int>(UpdateProgressBar), new Object[] { i });
  }
  else
  {
    Thread.Sleep(200);
    progressBar1.Refresh();
    progressBar1.Value = i;
    progressBar1.CreateGraphics().DrawString(i.ToString() + "%", new Font("Arial",
                                          (float)10.25, FontStyle.Bold),
                                          Brushes.Red, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
  }
}
