Answer 1

A simple one :

overrides check box OnPaint(PaintEventArgs e) as below:

Graphics g = e.Graphics;

        base.OnPaint(e);
        //// Fill the background
        //SetControlSizes();

        // Paint the outer rounded rectangle
        g.SmoothingMode = SmoothingMode.AntiAlias;
        using (GraphicsPath outerPath = GeneralUtilities.RoundedRectangle(mLabelRect, 1, 0))
        {
            using (LinearGradientBrush outerBrush = new LinearGradientBrush(mLabelRect,
                   mGradientTop, mGradientBottom, LinearGradientMode.Vertical))
            {
                g.FillPath(outerBrush, outerPath);
            }
            using (Pen outlinePen = new Pen(mGradientTop, mRectOutlineWidth))
            {
                outlinePen.Alignment = PenAlignment.Inset;
                g.DrawPath(outlinePen, outerPath);
            }
        }

        //// Paint the gel highlight
        using (GraphicsPath innerPath = GeneralUtilities.RoundedRectangle(mHighlightRect, mRectCornerRadius, mHighlightRectOffset))
        {
            using (LinearGradientBrush innerBrush = new LinearGradientBrush(mHighlightRect,
                   Color.FromArgb(mHighlightAlphaTop, Color.White),
                   Color.FromArgb(mHighlightAlphaBottom, Color.White), LinearGradientMode.Vertical))
            {
                g.FillPath(innerBrush, innerPath);
            }
        }
        // Paint the text
        TextRenderer.DrawText(g, Text, Font, mLabelRect, Color.White, Color.Transparent,
        TextFormatFlags.HorizontalCenter | TextFormatFlags.VerticalCenter | TextFormatFlags.EndEllipsis);

But if you want to have a good one you have to use wpf CheckBox ControlTemplate Example
