| 标题 | asp.net实现DataList与Repeater嵌套绑定的方法 |
| 内容 | 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 width="186" cellpadding="0" cellspacing="1"> <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。 |
