Repeater控件和DataList控件，可以用来一次显示一组数据项。比如，可以用它们显示一个数据表中的所有行。
Repeater控件完全由模板驱动，提供了最大的灵活性，可以任意设置它的输出格式。DataList控件也由模板驱动，和Repeater不同的是，DataList默认输出是HTML表格，DataList将数据源中的记录输出为HTML表格一个个的单元格 。1、Repeater支持以下5种模板：
● ItemTemplate : 对每一个数据项进行格式设置 （包含要为数据源中每个数据项都要呈现一次的 HTML 元素和控件。）。
● AlternatingItemTemplate : 对交替数据项进行格式设置（包含要为数据源中每个数据项都要呈现一次的 HTML 元素和控件。）。 ● SeparatorTemplate : 对分隔符进行格式设置（包含在每项之间呈现的元素。）。 ● HeaderTemplate : 对页眉进行格式设置（包含在列表的开始处分别呈现的文本和控件。）。 ● FooterTemplate : 对页脚进行格式设置（包含在列表的结束处分别呈现的文本和控件。）。示例一：（基本演示）

2、Repeater控件的嵌套：
示例一：（Repeater控件嵌套演示：操作子Repeater控件）
aspx页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RepeaterDemo._Default" %>
cs页面：
using System;using System.Collections.Generic;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace RepeaterDemo{ public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { List peopleList = new List (); peopleList.Add(new People("韩兆新",24,Sex.男)); peopleList.Add(new People("XXXX", 25, Sex.女)); peopleList.Add(new People("YYYY", 20, Sex.男)); peopleList.Add(new People("ZZZZ", 23, Sex.男)); peopleList.Add(new People("AAAA", 23, Sex.女)); peopleList.Add(new People("BBBB", 18, Sex.女)); rptPeople.DataSource = peopleList; rptPeople.DataBind(); } protected void rptPeople_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { List literaryList = new List (); literaryList.Add("《借我一生》"); literaryList.Add("《追风筝的人》"); literaryList.Add("《山居笔记》"); List scientificList = new List (); scientificList.Add("《时间简史》"); scientificList.Add("《果壳中的宇宙》"); scientificList.Add("《时空的未来》"); List philosophicList = new List (); philosophicList.Add("《周易正义》"); philosophicList.Add("《苏菲的世界》"); philosophicList.Add("《理想国》"); Repeater rptLiterary = e.Item.FindControl("rptLiterary") as Repeater; rptLiterary.DataSource = literaryList; rptLiterary.DataBind(); Repeater rptScientific = e.Item.FindControl("rptScientific") as Repeater; rptScientific.DataSource = scientificList; rptScientific.DataBind(); Repeater rptPhilosophic = e.Item.FindControl("rptPhilosophic") as Repeater; rptPhilosophic.DataSource = philosophicList; rptPhilosophic.DataBind(); } } } public enum Sex { 男 = 2, 女 = 1, }; public class People { public People(string name, uint age, Sex sex) { this.Name = name; this.Age = age; this.Sex = sex; } public string Name {get;set;} public uint Age { get; private set; } public Sex Sex { get; private set; } }} 示例二：（Repeater控件嵌套:获取父Repeater控件的值）
