 1、静态模板页面 template.html,主要是定义了一些特殊字符,用来被替换。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>$Title</title>
</head>
<body>
   <div style="width: 417px; height: 54px" align="center">
     <br />
   $Title</div>
   <div style="width: 417px; height: 8px">
     浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=$NewsId"></script></font>次  $Time</div>
   <div style="width: 417px; height: 100px">
     $Content</div>
   <div style="width: 416px; height: 9px">
     $Pager</div>
   <div style="width: 416px; height: 8px">
   <form id="form1" action="../AddComment.aspx" style="margin:0px">
     <input id="Text1" type="text" /><Img id="Image1" src="../../UserInfo/CheckCode.aspx"/><br />
     <textarea  id="CommentContent" cols="20" rows="2"></textarea>
     <br />
     <input id="NewsId" type="hidden" value="$NewsId"/>
     <input id="Button1" type="submit" value="button" />
     <a href="../Display.aspx?NewsId=$NewsId">查看更多评论</a></form>
     </div>
</body>
</html>

2、前态页面 NewsAdd.aspx,就是一个表单,用来填写新闻的标题和内容。

<%...@ Page Language="C#" AutoEventWireup="false" validateRequest="false" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd.Admin_AdminPanel_NewsAdd" %>
<%...@ Register TagPRefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
   <title>添加新闻</title>
</head>
<body>
   <form id="form1" runat="server">
   <div>
     <asp:Label ID="Label2" runat="server" Text="标题"></asp:Label>
     <asp:TextBox ID="Title" runat="server" Width="325px"></asp:TextBox><br />
     <asp:Label ID="Label1" runat="server" Text="内容"></asp:Label>
   <FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/"  runat="server" Height="400px" Width="70%"></FCKeditorV2:FCKeditor>
     <asp:Button ID="Button1" runat="server" Text="Button" />
     <asp:Label ID="Message" runat="server" ></asp:Label></div>
   </form>
</body>
</html>
