Answer 2

One way is to derive your own progressbar from the progressbar control, and then use PathGradientBrush or LinearGradientBrush to paint its color in the OnPaint method.

An example using PathGradientBrush:

    public class MyProgressBar : ProgressBar  
    {  
        public MyProgressBar()  
        {  
            this.SetStyle(ControlStyles.UserPaint, true);  
        }  
  
        protected override void OnPaint(PaintEventArgs e)  
        {  
            Rectangle rec = e.ClipRectangle;  
            GraphicsPath path = new GraphicsPath();  
            path.AddRectangle(rec);  
  
            PathGradientBrush pthGrBrush = new PathGradientBrush(path);  
  
            pthGrBrush.CenterColor = Color.FromArgb(255, 0, 0, 255);  
  
            Color[] colors = { Color.Red,Color.Yellow};  
            pthGrBrush.SurroundColors = colors;  
  
            rec.Width = (int)(rec.Width * ((double)Value / Maximum)) - 4;  
            if (ProgressBarRenderer.IsSupported)  
                ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle);  
            rec.Height = rec.Height - 4;  
            e.Graphics.FillRectangle(pthGrBrush, 2, 2, rec.Width, rec.Height);  
        }  
    }
