通用新闻文章系统标题列表用户控件，大大减少重复劳动

公司网站改版，使用了.net2.0，其中有大量的新闻文章系统的标题列表方式显示，算是最简单重复的劳动了，功能莫过于显示标题，截断标题，分类id，是否显示时间和点击次数等等，于是就构思着做了这个用户控件，使用很方便，只需要设置几个属性就可以工作了，不知道对你是否有价值呢？

ArticlesTitleList.ascx源代码：

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ArticlesTitleList.ascx.cs" Inherits="UserControls_ArticlesTitleList" EnableViewState="false"%>

<asp:Repeater ID="Repeater1" runat="server" EnableViewState="False">
<HeaderTemplate><ul></HeaderTemplate>
<ItemTemplate>
<li><%# DataBinder.Eval(Container.DataItem, "TheTitle")%><%# DataBinder.Eval(Container.DataItem, "EndInfo")%></li>

</ItemTemplate>
<FooterTemplate></ul></FooterTemplate>
</asp:Repeater>
<asp:Literal ID="ltlMore" runat="server"></asp:Literal>
