the grid border can not be replaced ,colorized or even erased, its native and as said i dont see any grid property to achieve that goal.
The posts i made produce a visual effect similar to border playing with borderwidth container property....resizing...
As pointed,there is many ways: shape ,container,drawing a box,Windows api to draw lines or vfp lines.... trying to hide the grid border.
this is very simple and basic .
if you have done a grid border with lines as you said ,please post a
complete workable code for demo .
