2 <asp:Repeater ID="Repeater1" runat="server" >

4     <ItemTemplate><li>标题：<%# Eval("sTitle")%></li></ItemTemplate>
5     <FooterTemplate></u1></FooterTemplate>
6 </asp:Repeater>

News_Tablist.ascx.cs

10 {
11     public partial class News_Tablist : System.Web.UI.UserControl
12     {
13         protected void Page_Load(object sender, EventArgs e)
14         {
15             if (!IsPostBack) {
16                 Response.Write("3333");
17                 var data = new T_NewsTableAdapter().GetDataByiType(iType);
18                 Repeater1.DataSource = data;
19                 Repeater1.DataBind();
20             }
21         }
