怎么样通过asp.net实现DataList与Repeater嵌套绑定?

怎么样通过asp.net实现DataList与Repeater嵌套绑定?

本文实例讲述了asp.net实现DataList与Repeater嵌套绑定的方法。分享给大家供大家参考,具体如下:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="home.aspx.cs" Inherits="home" %>
<body>
 <form id="form1" runat="server">
    <asp:DataList ID="monitorTypeList" runat="server" RepeatColumns="4" 
     onitemdatabound="monitorTypeList_ItemDataBound" RepeatDirection="Horizontal" ItemStyle-VerticalAlign="Top">
    <ItemTemplate>
    <table class="conBox" width="186" border="0" cellpadding="0" cellspacing="1" style="margin-right:10px;">
     <tr>
     <th><a href="<%#Eval("plugpath") %>"><%#Eval("monitor_type_name") %></a></th>
     </tr>
     <asp:Repeater ID="monitorConfigList" runat="server">
     <ItemTemplate>
     <tr>
     <td><a href="<%#Eval("plugpath") %>?monitor_id=<%#Eval("monitor_id") %>"><%#Eval("monitor_name") %></a></td>
     </tr>
     </ItemTemplate>
     </asp:Repeater>
    </table>
   </ItemTemplate>
   </asp:DataList>
 </form>
</body>

home.aspx.cs

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;
public partial class home : System.Web.UI.Page
{
 protected void Page_Load(object sender, EventArgs e)
 {
  myCheck.IsLoginNonReturn();
  if (!IsPostBack)
  {
   Bind_monitorTypeList();
  }
 }
 protected void Bind_monitorTypeList()
 {
  string sql = "select monitor_type_id,monitor_type_name from monitor_type";
  DbConn conn = new DbConn();
  DataSet ds = conn.DataSet(sql,"monitor_type");
  monitorTypeList.DataSource = ds.Tables[0];
  monitorTypeList.DataBind();
  ds.Dispose();
  conn.Close();
 }
 protected void monitorTypeList_ItemDataBound(object sender, DataListItemEventArgs e)
 {
  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  {
   string monitor_type_id = ((DataRowView)e.Item.DataItem).Row["monitor_type_id"].ToString();
   Repeater monitorConfigList = (Repeater)e.Item.FindControl("monitorConfigList");
   if (monitorConfigList != null)
   {
    string sql = "select monitor_id,nonitor_name,plugpath from monitor where monitor_type_id=" + monitor_type_id;
    DbConn conn = new DbConn();
    DataSet ds = conn.DataSet(sql, "monitor");
    monitorConfigList.DataSource = ds.Tables[0];
    monitorConfigList.DataBind();
    ds.Dispose();
    conn.Close();
   }
  }
 }
}

希望本文所述对大家asp.net程序设计有所帮助。
