Repeater嵌套绑定Repeater

cs代码：

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 }
