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[0];  //属性值
            dt_attrname = goodsmanagebll.Get_AdminGetAttributeListandValues(_cateid).Tables[1];  //属性名称

            if(dt_attrname.Rows.Count>0)
            {
               for (int i = 0; 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 = 0;

                   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;
                }
            }
