Answer 1

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {
            if (e.RowIndex == -1)
            {
                //绘制渐变列头
                //bool mouseOver = e.CellBounds.Contains(dataGridView1.PointToClient(Cursor.Position));
                //LinearGradientBrush brush = new LinearGradientBrush(
                //    e.CellBounds,
                //    mouseOver ? Color.PeachPuff : Color.LightGray,
                //    Color.DarkOrange,
                //    LinearGradientMode.Vertical);                //using (brush)
                //{
                //    e.Graphics.FillRectangle(brush, e.CellBounds);
                //    Rectangle border = e.CellBounds;
                //    border.Width -= 1;
                //    e.Graphics.DrawRectangle(Pens.Gray, border);
                //}                // 绘制背景色，不过这里的绘制无法连贯，你再研究一下吧。
                e.Graphics.DrawImage(global::WindowsApplication6.Properties.Resources.主页0, e.CellBounds.X, e.CellBounds.Y);
                
                e.PaintContent(e.CellBounds);
                e.Handled = true;
            }        }
