I have a tree-grid that I paint with these attributes:
SiwModifyStyle(
(__ESIS_STH_NONE|__ESIS_STV_ITEM) // Item scroll window styles
| __EGBS_SFB_FULL_ROWS // Selection/focus type - full row
| __EGBS_SF_SELECT_OUTER_ROWS // Cell selection when clicking row header
| __EGBS_DYNAMIC_RESIZING // Resize rows/columns on-the-fly
| __EGBS_GRIDLINES // Draw grid lines
| __EGBS_RESIZING_CELLS_OUTER, // enable row/column resizing
0, false);
SiwModifyStyleEx(
__EGBS_EX_CELL_TOOLTIPS_INNER
| __EGBS_EX_CELL_EXPANDING_INNER
| __EGWS_EX_PM_COLORS
| __EGBS_EX_CORNER_AREAS_3D
| __EGBS_EX_CORNER_AREAS_CURVE
| __EGBS_EX_HVI_EVENT_CELLS,
0, false);
BseModifyStyleEx( __EGBS_BSE_EX_PROPORTIONAL_COLUMN_WIDTHS); And OnTreeGridQueryDrawOutline returns false, so there are no outlines. However, the top-left corner of the cells is not painted properly, as you can see in this zoomed snapshot:

Thank you for reporting the problem. You can fix it in this way. In the CExtGridBaseWnd::OnGbwPaintCell method, update the following code block at the very end of the method: if( bGridLinesHorz || bGridLinesVert )
{
COLORREF clrFace = OnGbwQueryGridLinesColor();
if( bGridLinesHorz )
{
dc.FillSolidRect( rcCell.left - 1, rcCell.top - 1, rcCell.right - rcCell.left, 1, clrFace );
dc.FillSolidRect( rcCell.left - 1, rcCell.bottom - 1, rcCell.right - rcCell.left, 1, clrFace );
} // if( bGridLinesHorz )
if( bGridLinesVert )
{
dc.FillSolidRect( rcCell.left - 1, rcCell.top, 1, rcCell.bottom - rcCell.top, clrFace );
dc.FillSolidRect( rcCell.right - 1, rcCell.top, 1, rcCell.bottom - rcCell.top, clrFace );
} // if( bGridLinesVert )
} // if( bGridLinesHorz || bGridLinesVert )
