ascx可不可以从别的项目COPY呀？如果行的话，要注意些什么东东？

可以，不过要注意名字空间；还要注意ascx里面不能有<html>、<head>、<title>、<body>之类的标记。

这是我试的结果：分析器错误信息: 未能加载类型“NWebProject.WebControls.CN.SupplyDemand.LatestProduct”。源错误:
行 1：  <%@ Control Language="c#" AutoEventWireup="false" Codebehind="LatestProduct.ascx.cs" Inherits="NWebProject.WebControls.CN.SupplyDemand.LatestProduct" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
行 2：  <asp:datalist id="DataList1" runat="server" RepeatDirection="Horizontal" Width="100%" RepeatColumns="5">
行 3：   <ItemStyle HorizontalAlign="Center"></ItemStyle>

不知乍么解决，请各位大侠帮帮忙，多谢先！

可以，要注意和其他项目相关一些属性去掉！比如命名空间，还有html页面的一写东东

namespace WebProject.WebControls.CN.SupplyDemand
我想这个没错吧。<%@ Control Language="c#" AutoEventWireup="false" Codebehind="LatestProduct.ascx.cs" Inherits="WebProject.WebControls.CN.SupplyDemand.LatestProduct" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
这个是我的命名空间。

要在HTML页面加像<%@ Register TagPrefix="uc1" TagName="Header" Src="Header.ascx" %>只类的东西

lastestproduct.ascx.cs的代码是这样的.
namespace WebProject.WebControls.CN.SupplyDemand

<%@ Register TagPrefix="uc1" TagName="LatestProduct" Src="../WebControls/CN/SupplyDemand/LatestProduct.ascx" %>这个是我在首页上index.aspx上顶部加的。

LatestProduct.ascx要加入到项目中，然后再重新编译项目。

<%@ Control Language="c#" AutoEventWireup="false" Codebehind="LatestProduct.ascx.cs" Inherits="WebProject.WebControls.CN.SupplyDemand.LatestProduct" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>

<%# GetPdtName(DataBinder.Eval(Container, "DataItem.Pdt_Name","{0}")) %>
</a>
</TD>
</TR>
</TABLE>
</ItemTemplate>
</asp:datalist>这个就是报错的页面了！分析器错误信息: 未能加载类型“WebProject.WebControls.CN.SupplyDemand.LatestProduct”。源错误:
行 1：  <%@ Control Language="c#" AutoEventWireup="false" Codebehind="LatestProduct.ascx.cs" Inherits="WebProject.WebControls.CN.SupplyDemand.LatestProduct" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>

哇哇哇，下班班啦！不搞掂BOSS会打小PP的
