repeater之嵌套绑定，使用初学者。。

 废话不多说了，我就直接上代码了。。

  

    以下是cs代码：

 

 1  //下拉绑定
 2         void autoOldbind()
 3         {
 4             this.DropDownList1.DataSource = OldBLL.QueryAll();
 5             this.DropDownList1.DataTextField = "OldName";
 6             this.DropDownList1.DataValueField = "ID";
 7             this.DropDownList1.DataBind();
 8         }
 9         //大类绑定
10         void autobind()
11         {
12             this.auto_repOld.DataSource = OldBLL.QueryAll();
13             this.auto_repOld.DataBind();
14         }
15 
16         //嵌套绑定
17         protected void repeat_dataBind(object sender, RepeaterItemEventArgs e)
18         {
19             Repeater rep = e.Item.FindControl("auto_repyong") as Repeater;//找到里层的repeater对象
20             //DataRowView row = (DataRowView)e.Item.DataItem;
21             _Old dv = (_Old)e.Item.DataItem;
22             //提取大类ID
23             int CategorieId = Convert.ToInt32(dv.ID);
24             _Young y = new _Young();
25             y.OldID = CategorieId;
26             rep.DataSource = YoungBLL.QueryYoung(y);
27             rep.DataBind();
28         }
29 
30         //增增小类
31         protected void Button1_Click(object sender, EventArgs e)
32         {
33             _Young y = new _Young();
34             string youngtest = this.TextBox1.Text.Trim();
35             int OLdIndex =Convert.ToInt32(this.DropDownList1.SelectedItem.Value);
36             y.OldID = OLdIndex;
37             y.YoungName = youngtest;
38             YoungBLL.AddYoung(y);
39             autobind();
40             this.auto_repOld.ItemDataBound += new RepeaterItemEventHandler(repeat_dataBind);
41         }
View Code

 以下是操作界面：

欢迎大家来拍砖。。
