//关键   Gridview 添加关系
                if (prefix == "Orders")
                    gridControl1.LevelTree.Nodes.Add(prefix, gvs[i]);
                else if (prefix != "")
                    gridControl1.LevelTree.Nodes["Orders"].Nodes.Add(prefix, gvs[i]);
            }
        }

效果:

想起做这个效果的表，是因为Bom层次显示的时候需要这样。

如果加一列CheckBox，可以在计算物理需求时选择参加计算的物料。
