在ascx文件中使用Repeater动态加载数据：News_Tablist.ascx

[u]复制代码[/u] 代码如下:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="News_Tablist.ascx.cs" Inherits="协同企业管理系统.admin.News_Tablist" %>
 <asp:Repeater ID="Repeater1" runat="server" >
     <HeaderTemplate><ul></HeaderTemplate>
     <ItemTemplate><li>标题：<%# Eval("sTitle")%></li></ItemTemplate>
     <FooterTemplate></u1></FooterTemplate>
 </asp:Repeater>

News_Tablist.ascx.cs

[u]复制代码[/u] 代码如下:

using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Web.UI;
 using System.Web.UI.WebControls;
 using 协同企业管理系统.DAL.DataSetNewsTableAdapters;

 namespace 协同企业管理系统.admin
 {
     public partial class News_Tablist : System.Web.UI.UserControl
     {
         protected void Page_Load(object sender, EventArgs e)
         {
             if (!IsPostBack) {
                 Response.Write("3333");
                 var data = new T_NewsTableAdapter().GetDataByiType(iType);
                 Repeater1.DataSource = data;
                 Repeater1.DataBind();
             }
         }

         public int iType
         {
             get;
             set;
         }
     }
 }
