What is the grid you are referring to?

If you are talking about a grid-layer as a background, the GEF already have it included (in either FreeformGraphicalRootEditPart or ScalableRootEditPart). You just need to activate it by setting a flag in your viewer.

in a subclass of GraphicalEditor:

    protected void configureGraphicalViewer () {
        ......
        viewer.setProperty (SnapToGrid.PROPERTY_GRID_VISIBLE, Boolean.TRUE);
        ......
    }

Just use org.eclipse.draw2d.GridLayout as your layout manager.
