If the Orientation is Orientation.Vertical, for example, this method will position all of the objects in the document in the grid, specified by GoView.GridCellSizeWidth, GoView.GridCellSizeHeight, GoView.GridOriginX, and GoView.GridOriginY, starting at the top left corner, and proceeding to fill each row before adding rows. The order in which document objects are taken as palette items is determined by the Sorting and the Comparer comparison method.
