    文章详情后台代码：News_detail.aspx.cs
    复制代码 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_detail : System.Web.UI.Page
         {
             protected void Page_Load(object sender, EventArgs e)
             {
                 if (!IsPostBack) {
                     int ID = Convert.ToInt32(Request["ID"]);
                     var NewsTable = new T_NewsTableAdapter().GetDataById(ID);
                     if (NewsTable.Count <= 0)

                     }
                 }
             }
         }
     }

    在ascx文件中使用Repeater动态加载数据：News_Tablist.ascx
    复制代码 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" %>
     
        

          
    • 标题：<%# Eval("sTitle")%>

      •     
       

    News_Tablist.ascx.cs
    复制代码 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;
             }
         }
     }

    附件上传页面：Pic_load.aspx
    复制代码 代码如下:
