Maybe one possible solution could be if you are using:

public partial class Form1 : Form

{

    private BackgroundWorker backgroundWorker1;

  public Form1()

   {

       InitializeComponent();

    this.backgroundWorker1 = new System.ComponentModel.BackgroundWorker();

    backgroundWorker1.DoWork +=new DoWorkEventHandler(backgroundWorker1_DoWork);

   }

  void backgroundWorker1_DoWork(object sender, DoWorkEventArgse)

   {

    for (int i = 0; i <= 100; i++)

      {

       // Just do delay in the background process

      DateTime tempValue = DateTime.Now;

      while (tempValue.AddSeconds(1) > DateTime.Now)

          {

           Debug.WriteLine(DateTime.Now.ToString());

          }

      this.ultraStatusBar1.Panels[0].ProgressBarInfo.Value = i;

      this.ultraStatusBar1.Panels[1].ProgressBarInfo.Value = i;

      this.ultraStatusBar1.Invoke((MethodInvoker)delegate()

         {

           this.ultraStatusBar1.Panels[1].Text = "Loading " + ultraStatusBar1.Panels[1].ProgressBarInfo.Value.ToString() + " %";

         });

        }

  }

private void ultraButton1_Click(object sender, EventArgs e)

  {

  this.backgroundWorker1.RunWorkerAsync();

  }

}

Please take a look at the attached sample for more details and let me know if you have any questions
