我正在使用Telerik列表视图。我刚刚添加了一个SqlDataSource，我想在服务器端给出select命令。但是当我想在.cs文件中访问它时，即使没有显示任何控件，也无法访问SqlDataSource1。当我尝试使用Label1.Text时，我添加了一个标签，而不是.cs文件中无法访问label1。

可能是因为您没有提到哪个是您网页的代码隐藏。将其添加为aspx页面的第一行
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="yourfile.aspx.cs" Inherits="YourProjectName.YourASPXPageName" %>
答案 1 :(得分：0)
您的内容占位符中不允许使用某些内容，因为您使用的是主文件。你没有对你的控件进行智能感知的原因是因为该页面不会被压缩。
删除这些标记：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<body>
<form id="form1" runat="server">
然后尝试编译您的应用。修复编译器抛出的任何错误并重新编译。一旦应用程序可编译，您的intellisense应该重新开始工作。

是的我在这里找到了解决方案......我必须通过右键单击“项目文件夹”并单击“转换为Web应用程序”将其转换为Web应用程序。比它的intellisense开始工作。
