If you don't see the grid, it could be because one of your layers above the
grid layer is opaque or something. If you can't snap to the grid, it could
be because your editpart is not returning SnapToGrid helper from its
getAdapter() method. I believe the steps to create the grid have been
discussed on this newsgroup before, so just search for it. Post again if
you're still having problems.

I do not know how to find the layers above grid layer, and how to set
them opaque. I am confused if I missed something. I searched the mails in
the newsgroup but it didn't help me. Plz suggest something or provide some
steps.

I have tested my program with the following code in contributeToToolBar
toolBarManager.add(getAction(GEFActionConstants.TOGGLE_GRID_ VISIBILITY));
Selecting/ unselecting the button is not showing the grid. Moreover it
also not worked with blank canvas (i think that no layers are there in a
blank canvas, so no question of opaque).
Kindly help...
Regards,
Nitin.

The layers above the gird layer need to be transparent, not opaque, for the
grid to be visible. And by default, they are. You just need to make sure
you're not setting anything to opaque. Any opaque figures will also cover
up parts of the grid.
Are your EditParts returning SnapToGrid from their getAdapter() method? Is
the snapping happening when you drag your editparts around (it can happen
even if the grid is not visible)?

So, why was the grid not visible earlier?
SnapToGeometry is not the same as SnapToGrid.
