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

 1  DataTable dt_attrname = new DataTable();
 2             DataTable dt_valuename = new DataTable();
 3             dt_valuename = goodsmanagebll.Get_AdminGetAttributeListandValues(_cateid).Tables[0];  //属性值
 4             dt_attrname = goodsmanagebll.Get_AdminGetAttributeListandValues(_cateid).Tables[1];  //属性名称
 5
 6             if(dt_attrname.Rows.Count>0)
 7             {
 8                for (int i = 0; i < dt_attrname.Rows.Count; i++)
 9                // for (int i = 0; i < 1; i++)
10                 {
11                     ASPxLabel lb = new ASPxLabel();
12                     lb.Text = dt_attrname.Rows[i]["ATTRNAME"].ToString();
13
14                     ASPxPanel1.Controls.Add(lb);
15                    //li.Controls.Add(lb);
16
17                    DataRow[] dr = dt_valuename.Select(" attrid = " + dt_attrname.Rows[i]["attrid"].ToString());
18
19                    ASPxCheckBoxList aspxcheckboxlist = new ASPxCheckBoxList();
20                    aspxcheckboxlist.Border.BorderStyle = 0;
21
22                    aspxcheckboxlist.RepeatDirection = RepeatDirection.Horizontal;
23
24                    foreach (DataRow dr1 in dr)
25                    {
26                        ListEditItem lei = new ListEditItem();
27
28                        lei.Text = dr1["ATTRVALUE"].ToString();
29                        lei.Value = dr1["ATTRVALUEID"].ToString();
30
31                        aspxcheckboxlist.ID = "ck" + i;
32                        aspxcheckboxlist.Items.Add(lei);
33
34                    }
35
36                    // li.Controls.Add(aspxcheckboxlist);
37                    ASPxPanel1.Controls.Add(aspxcheckboxlist);
38
39                  // ASPxCheckBoxList ckboxlist = this.ASPxPanel1.FindControl("ck0") as ASPxCheckBoxList;
40                 }
41             }
