Repeater的嵌套
经常会遇到需要嵌套的地方，比如说回复帖子等，这时候可以使用Repeater来进行嵌套，据说同样适用于DataList，代码如下：
ASPX代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="wwt.UI.WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
<style type="text/css">
ul{
list-style: none;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<ul>
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<li>
<%#Eval("Body")%>
</li>
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<li style="text-indent:24px;">
<%#Eval("Body")%>
</li>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
</ul>
</div>
</form>
</body>
</html>CS代码：
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using wwt.SQLServerDAL;
namespace wwt.UI
{
public partial class WebForm1 : System.Web.UI.Page
{
wwt.SQLServerDAL.Space SpaceDal = new wwt.SQLServerDAL.Space();
protected void Page_Load(object sender, EventArgs e)
{
//绑定外层的Repeater1
this.Repeater1.DataSource = SpaceDal.GetAlbumCommonListByID(101011, 0).Tables[0];
this.Repeater1.DataBind();
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
//判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，
//HeaderTemplate，，ItemTemplate，SeparatorTemplate）
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater rep = e.Item.FindControl("Repeater2") 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["id"]); //获取填充子类的id
rep.DataSource = SpaceDal.GetAlbumCommonListByID(101011, typeid).Tables[0];
rep.DataBind();
}
}
}
