最近有朋友想让我给他做个手机上页面，页面功能是显示省--市--区--门店信息，这种层级关系的数据，首先来看看效果；
我想现在的手机都是智能机了对于普通的asp.net页面开发应该没什么两样，不过最终开发下来还是有点区别：
1：首先是Safari浏览器对js的支持，和IE下面的区别。
2：页面数据的显示以及缩放等效果。
介于以上要求，我考虑使用Repeater多层嵌套来实现，下面是页面代码：

<style>

后台代码主要是查询数据库，并且多层绑定数据到Repeater对象上，下面是给出的后台代码：

using System.Data;
using System.Configuration;

{
string sql = " SELECT distinct smc FROM dt1 ";
if (!IsPostBack)
{
DataTable dt_sheng = getData(sql).Tables[]; rp_sheng.DataSource = dt_sheng;
rp_sheng.DataBind();
}
} public DataSet getData( string sql)
{ string connection = "Provider=Microsoft.Jet.OLEDB.4.0;Server=MyMDB.mdb";
string dbConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:/Inetpub/wwwroot/WebSite/App_Data/fu.mdb"; System.Data.OleDb.OleDbConnection oleDbConnection = new System.Data.OleDb.OleDbConnection(dbConn); DataSet ds = new DataSet(); System.Data.OleDb.OleDbDataAdapter oleDataAdapter = new System.Data.OleDb.OleDbDataAdapter(sql, oleDbConnection); oleDbConnection.Open();
oleDataAdapter.Fill(ds);
oleDataAdapter.Dispose();
oleDbConnection.Close();
return ds;
} protected void rp_sheng_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater rep = e.Item.FindControl("rp_shi") as Repeater;//找到里层的repeater对象
DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项
//int typeid = Convert.ToInt32(rowv["smc"]); //获取填充子类的id
string sql = "SELECT distinct csmc FROM dt1 where smc='" + rowv["smc"] + "'";

rep.DataBind();
}
} protected void rp_shi_ItemDataBound(object sender, RepeaterItemEventArgs e)
{

{
