We modified the following method for painting a custom border around button cells in the inner grid area only: void CNxL_MlGrid::OnGbwPaintCell(
CDC & dc,
LONG nVisibleColNo,
LONG nVisibleRowNo,
LONG nColNo,
LONG nRowNo,
const RECT & rcCellExtra,
const RECT & rcCell,
const RECT & rcVisibleRange,
DWORD dwAreaFlags,
DWORD dwHelperPaintFlags
) const
{
//--note
// ƒtƒH[ƒJƒX‚ª‚È‚¬‚Ä‚àŽ©g‚ªƒtƒH[ƒJƒX‚³‚ê‚Ä‚¢‚é‚Æ‚¢‚¤ƒtƒ‰ƒO‚𗧂Ăé
dwHelperPaintFlags |= __EGCPF_FOCUSED_CONTROL;
CExtGridWnd::OnGbwPaintCell( dc,
nVisibleColNo,
nVisibleRowNo,
nColNo,
nRowNo,
rcCellExtra,
rcCell,
rcVisibleRange,
dwAreaFlags,
dwHelperPaintFlags
);
if( ( dwAreaFlags & __EGBWA_INNER_CELLS ) != 0 )
{ // if inner data cell
const CExtGridCell * pCell = GridCellGet( nColNo, nRowNo );
if( pCell != NULL && pCell->IsKindOf( RUNTIME_CLASS(CExtGridCellButton) ) )
{ // if button cell
COLORREF clr1tl = RGB(192,0,0), clr1rb = RGB(128,0,0);
CRect rc = rcCell;
dc.Draw3dRect( &rc, clr1tl, clr1rb );
rc.DeflateRect( 1, 1 );
COLORREF clr2tl = RGB(255,0,0), clr2rb = RGB(144,0,0);
dc.Draw3dRect( &rc, clr2tl, clr2rb );
} // if button cell
} // if inner data cell
}Is that what you need?

Hello First of all,
Because a line can draw, it is OK.
Why cannot a line actually draw with this sample?
I asked you a question. Thanks,

Please let us know more details about your task. Which lines exactly do you need?
Your screen shots displaying default looking button cells. Do you need to customize the look of button?

The push button is painted in the CExtGridCell::OnPaintButton() virtual method. This method paints the button using the CExtPaintManger::Grid_PaintButton() method. The button’s look depend on which paint manager is used. But generally there are no fill color and button color based rules for button painting. The skin, native XP and Office 2007 paint manager are using bitmap based button shapes. So, you should implement the CExtGridCell::OnPaintButton() virtual method and completely repaint the button if you need some frame around it and some preferred button color.
