如何在后台动态生成ASPxCheckBoxList标签并循环（数据调用存储过程）

  DataTable dt_attrname = new DataTable();
             DataTable dt_valuename = new DataTable();
             dt_valuename = goodsmanagebll.Get_AdminGetAttributeListandValues(_cateid).Tables[];  //属性值
             dt_attrname = goodsmanagebll.Get_AdminGetAttributeListandValues(_cateid).Tables[];  //属性名称

             if(dt_attrname.Rows.Count>)
             {
                for (int i = ; i < dt_attrname.Rows.Count; i++)
                // for (int i = 0; i < 1; i++)
                 {
                     ASPxLabel lb = new ASPxLabel();
                     lb.Text = dt_attrname.Rows[i]["ATTRNAME"].ToString();

                     ASPxPanel1.Controls.Add(lb);
                    //li.Controls.Add(lb);

                    DataRow[] dr = dt_valuename.Select(" attrid = " + dt_attrname.Rows[i]["attrid"].ToString());

                    ASPxCheckBoxList aspxcheckboxlist = new ASPxCheckBoxList();
                    aspxcheckboxlist.Border.BorderStyle = ;

                    aspxcheckboxlist.RepeatDirection = RepeatDirection.Horizontal;

                    foreach (DataRow dr1 in dr)
                    {
                        ListEditItem lei = new ListEditItem();

                        lei.Text = dr1["ATTRVALUE"].ToString();
                        lei.Value = dr1["ATTRVALUEID"].ToString();

                        aspxcheckboxlist.ID = "ck" + i;
                        aspxcheckboxlist.Items.Add(lei);

                    }

                    // li.Controls.Add(aspxcheckboxlist);
                    ASPxPanel1.Controls.Add(aspxcheckboxlist);

                  // ASPxCheckBoxList ckboxlist = this.ASPxPanel1.FindControl("ck0") as ASPxCheckBoxList;
                 }
             }
