Asp控件不工作
Asp控件不工作
提问于 2012-07-15 00:11:42
我正在尝试使用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，SqlDataSource1是不可访问的，甚至任何控件都没有显示。我在尝试Label1.Text时添加了一个标签，因为在.cs文件中无法访问label1。

这是可能的，因为你没有提到哪个是你页面的代码隐藏。将此代码作为第一行添加到aspx页面

您的内容占位符中有一些不允许的内容，因为您使用的是母版。你没有在你的控件上获得智能感知的原因是因为页面不会编译。
删除这些标记：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<body>
<form id="form1" runat="server"> 然后尝试编译你的应用程序。修复编译器抛出的任何错误，然后重新编译。一旦应用程序可编译，您的intellisense就应该重新开始工作。

是的，我在这里找到了解决方案……我必须通过右键单击ProjectFolder并单击“转换为Web应用程序”将其转换为webApplication。然后它的智能感知开始工作。
