i dont white lines seen

as option can set border styles yo none:

me.datagridview1.cellborderstyle = datagridviewcellborderstyle.none

then handle cellpainting event , paint borders:

private sub datagridview1_cellpainting(sender object, _     e datagridviewcellpaintingeventargs) handles datagridview1.cellpainting      if (e.columnindex < 0 orelse e.rowindex < 0) return     e.paint(e.cellbounds, datagridviewpaintparts.all)     dim r = e.cellbounds     e.graphics.drawline(pens.black, r.left, r.top, r.right, r.top)     e.graphics.drawline(pens.black, r.left, r.bottom, r.right, r.bottom)     e.handled = true end sub
