    FarPoint.Win.Spread.DrawingSpace.GradientSection grd = new FarPoint.Win.Spread.DrawingSpace.GradientSection(Color.Empty);
    grd.AlphaBlend = 255;
    grd.Amount = 50;
    grd.Color = Color.Red;
    
    FarPoint.Win.Spread.DrawingSpace.RectangleShape rs = new FarPoint.Win.Spread.DrawingSpace.RectangleShape();
    rs.Name = "GradientRect";
    
    rs.Gradient.Style = FarPoint.Win.Spread.DrawingSpace.GradientStyle.RadialFromCenter;
    rs.Gradient.Sections[0] = grd;
    
    fpSpread1.ActiveSheet.AddShape(rs);
    
    Dim grd As New FarPoint.Win.Spread.DrawingSpace.GradientSection(Color.Empty)
    grd.AlphaBlend = 255
    grd.Amount = 50
    grd.Color = Color.Red
