我们已经简单的了解了repeater的处理方式。

这篇文章主要介绍 Asp.net 通过Repeater嵌套Repeater循环添加对应的一组控件的实现方式。

后台代码：

using System;using System.Collections;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace EricSunWebAppProject{    public partial class TestNestedRepeatorControl : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            if (!Page.IsPostBack)            {                ArrayList provinceList = new ArrayList();                ArrayList lnCityList = new ArrayList();                ArrayList jlCityList = new ArrayList();                lnCityList.Add(new CityInfo("dalian", "116000"));                lnCityList.Add(new CityInfo("shenyang", "110000"));                provinceList.Add(new ProvinceInfo("LiaoNing", lnCityList));                jlCityList.Add(new CityInfo("changchun", "130000"));                jlCityList.Add(new CityInfo("jilin", "132000"));                provinceList.Add(new ProvinceInfo("JiLin", jlCityList));                this.ProvinceRepeater.DataSource = provinceList;                this.ProvinceRepeater.DataBind();            }        }        protected void ProvinceRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)        {            // This event is raised for the header, the footer, separators, and items.            // Execute the following logic for Items and Alternating Items.            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)            {                Repeater cityRep = (Repeater)e.Item.FindControl("CityRepeater");                cityRep.DataSource = ((ProvinceInfo)e.Item.DataItem).Cities;                cityRep.DataBind();            }        }        protected void CityRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)        {            // This event is raised for the header, the footer, separators, and items.            // Execute the following logic for Items and Alternating Items.            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)            {                if (((CityInfo)e.Item.DataItem).CityName == "dalian")                {                    ((Label)e.Item.FindControl("CityNameLabel")).Text = "*dalian*";                }            }        }    }    public class ProvinceInfo    {        private string provincename;        private ArrayList cities;        public ProvinceInfo(string name, ArrayList cityList)        {            provincename = name;            cities = cityList;        }        public string ProvinceName        {            get            {                return provincename;            }        }        public ArrayList Cities        {            get            {                return cities;            }        }    }    public class CityInfo    {        private string cityname;        private string postcode;        public CityInfo(string name, string code)        {            cityname = name;            postcode = code;        }        public string CityName        {            get            {                return cityname;            }        }        public string PostCode        {            get            {                return postcode;            }        }    }}
