My code goes like th

Answer 1

Should be

e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom-1 , e.CellBounds.Right - 1, e.CellBounds.Bottom - 1);

e.CellBounds.Right, e.CellBounds.Bottom - 1 point would be erased by next cell.

Answer 2

i am not sure why you need to catch CellPainting event to change cell background color just do it like this

Daywisegrid.Rows[RowIndex].Cells[columnIndex].Style.BackColor = Color.Red;

But if you want to do it in painting try this

private void Daywisegrid_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {
            if (e.RowIndex == 0 )

            {
                using (Brush gridBrush = new SolidBrush(this.Daywisegrid.GridColor))
                {
                    using (Brush backColorBrush = new SolidBrush(e.CellStyle.BackColor))
                    {
                        using (Pen gridLinePen = new Pen(gridBrush))
                        {
                            // Clear cell 
                            e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
                            //Bottom line drawing
                            e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom-1 , e.CellBounds.Right, e.CellBounds.Bottom-1);

                              // here you force paint of content
                             e.PaintContent( e.ClipBounds  );
                            e.Handled = true;
                        }
                    }
                }
            }
