Asp.net 通过Repeater嵌套Repeater循环添加对应的一组控件

有了上篇文章的介绍 http://www.cnblogs.com/mingmingruyuedlut/archive/2013/04/02/2987096.html

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 = "<b>*dalian*</b>";
                }
            }
        }
    }

    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;
            }
        }
    }
}
