Why doesn't it paint the button with a gradient?

Question

C++ / C#

protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            this.Paint += FlatButton_Paint;
            using (LinearGradientBrush linGrBrush = new LinearGradientBrush(new Point(borderRectangle.Left), new Point( borderRectangle.Right), Color.FromArgb(255, 248, 140, 17), Color.FromArgb(255, 241, 99, 21)))
            {
              e.Graphics.FillRectangles(linGrBrush);
            }
        }

I need the created button to be filled with a gradient, but for some reason it gives an error, what's the problem?

Answer 1

What error appears?
Perhaps you need to pass 2 parameters to the FillRectangles function ?
