Devexpress中Gridcontrol查找分组

devexpress中gridcontrol查找分组 ，具体代码如下所述：

private void button1_click(object sender, eventargs e)
    {
      datatable dt = new datatable();
      dt.columns.add("group");
      dt.columns.add("idex");
      dt.columns.add("name");
      for (int i = 0; i < 5; i++)
      {
        datarow dr = dt.newrow();
        dr["group"] = "<5";
        dr["idex"] = i.tostring();
        dr["name"] = "姓名" + i.tostring();
        dt.rows.add(dr);
      }
      for (int i = 5; i <= 10; i++)
      {
        datarow dr = dt.newrow();
        dr["group"] = "(5,10]";
        dr["idex"] = i.tostring();
        dr["name"] = "姓名" + i.tostring();
        dt.rows.add(dr);
      }
      for (int i = 10; i <= 15; i++)
      {
        datarow dr = dt.newrow();
        dr["group"] = "(10,15]";
        dr["idex"] = i.tostring();
        dr["name"] = "姓名" + i.tostring();
        dt.rows.add(dr);
      }
      gridcolumnnumber.fieldname = "idex";
      gridcolumnname.fieldname = "name";
      gridcolumngroup.fieldname = "group";
      gridcolumngroup.groupindex = 0;
      gdc.datasource = dt;
      gdv.expandallgroups();
      for (int i = -1; gdv.isgrouprow(i); i--)
      {
        datarow dr = gdv.getdatarow(gdv.getdatarowhandlebygrouprowhandle(i));
        if (dr == null) return;
        if (dr["group"].tostring() == "(5,10]")
        {
          gdv.collapseallgroups();
          gdv.focusedrowhandle = i;
          gdv.setrowexpanded(i, true);
          return;
        }
      }
    }
