DataSet dsset = _rs.ExecuteSPForDS("Pro_xxxx", connstr, parameters);
??????????? DataColumn[] _obj1={dsset.Tables["ds1"].Columns["PRODUCT_NO"],dsset.Tables["ds1"].Columns["parent_id"]};
????????????? DataColumn[] _obj2={dsset.Tables["ds2"].Columns["PRODUCT_NO"],dsset.Tables["ds2"].Columns["parent_id"]};
??????????? dsset.Relations.Add("狀態(tài)二", dsset.Tables["ds"].Columns["PRODUCT_NO"], dsset.Tables["ds1"].Columns["PRODUCT_NO"]);
??????????? //dsset.Relations.Add("關(guān)系1", dsset.Tables["ds1"].Columns["parent_id"], dsset.Tables["ds2"].Columns["parent_id"]);
??????????? dsset.Relations.Add("狀態(tài)三", _obj1, _obj2);
?????????? this.gridControl1.DataSource = dsset.Tables[0];

注意點(diǎn)：加入第二個(gè)gridview ,levelname必須是關(guān)系名也就是上面的狀態(tài)二
