Repeater嵌套绑定Repeater

 c#:

View Code 
 1 private void RpTypeBind()
 2         {//GetQuestionTypeAndCount() 返回一个datatable
 3             this.rptypelist.DataSource = LiftQuestionCtr.GetQuestionTypeAndCount();                   
 4             this.rptypelist.DataBind();
 5         }
 6                protected void rptypelist_ItemDataBound(object sender, RepeaterItemEventArgs e)
 7         {
 8 
 9 //判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，
10 
11 //HeaderTemplate，，ItemTemplate，SeparatorTemplate）
12             if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
13             {
14                 Repeater rep = e.Item.FindControl("rpquestionlist") as Repeater;//找到里层的repeater对象
15                 DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
16                 int typeid = Convert.ToInt32(rowv["qtid"]); //获取填充子类的id 
17                 rep.DataSource = LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);
18                 rep.DataBind();
19             }
20         }
