{   
    if (e.Progress < 50)
    {
        this.linearProgressBar.ProgressColor = Android.Graphics.Color.Red;

		circularProgressBar = new SfCircularProgressBar(this);

		circularProgressBar.Minimum = 100;

		circularProgressBar.Maximum = 500;

		circularProgressBar.Progress = 500;

		circularProgressBar.ProgressCompleted += this.ProgressBarBase_OnProgressCompleted;

        circularProgressBar.Content = new TextView(this);

		(circularProgressBar.Content as TextView).SetText("Start", TextView.BufferType.Normal);

        SetContentView(circularProgressBar);
}

private void ProgressBarBase_OnProgressCompleted(object sender, ProgressValueEventArgs e)
{
    if (e.Progress.Equals(this.circularProgressBar.Maximum))
    {
       (this.circularProgressBar.Content as TextView).SetText("Completed", TextView.BufferType.Normal);
    }
