this is not good for real application, but if you Have TO do this, you can use this 

//subscribing the event
dataGridView1.CellPainting += dataGridView1_CellPainting;

//handle the event
void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{

    if (e.RowIndex >= 0 && e.ColumnIndex >= 0)
    {
        e.Graphics.DrawLine(Pens.Red, e.CellBounds.Left, e.CellBounds.Top, e.CellBounds.Right, e.CellBounds.Bottom);
        e.Graphics.DrawLine(Pens.Blue, e.CellBounds.Left, e.CellBounds.Top+e.CellBounds.Height / 2, e.CellBounds.Right,e.CellBounds.Top+ e.CellBounds.Height / 2);

        e.Paint(e.ClipBounds, DataGridViewPaintParts.ContentForeground);
        e.Handled = true;
    }
}

and the result is same as this:

But, As I told before, don't use this to real application
