VS阻塞的有效语法:

<input type="checkbox" name="roles" value='<%# Eval("Name") %>' 
  <%# ((bool) Eval("InRole")) ? "checked" : "" %> 
  <%# ViewData.Model.IsInRole("Admin") ? "" : "disabled" %> />

我的团队经常使用这个方法:

WebRequest myRequest = WebRequest.Create("http://www.google.com");
WebResponse myResponse = myRequest.GetResponse();
StreamReader sr = new StreamReader(myResponse.GetResponseStream());

// here's page's response loaded into a string for further use

String thisReturn = sr.ReadToEnd().Trim();

它以字符串的形式加载网页的响应。你也可以发送post参数。

当我们需要一些便宜和快速的东西时，我们用它来代替ASCX/AJAX/WebServices。基本上，它是一种跨服务器访问web可用内容的快速方法。事实上，我们昨天刚刚把它命名为“乡下人网络服务”。

HttpContext。项作为请求级缓存工具

你知道可以用ASP。IIS或Visual Studio之外的网络?

整个运行时都打包好了，可以在任何想要尝试的进程中托管。使用ApplicationHost, HttpRuntime和HttpApplication类，你也可以打磨这些.aspx页面，并从中得到漂亮的HTML输出。

HostingClass host = ApplicationHost.CreateApplicationHost(typeof(HostingClass), 
                                            "/virtualpath", "physicalPath");
host.ProcessPage(urlToAspxFile); 

你的主持课程:

public class HostingClass : MarshalByRefObject
{
    public void ProcessPage(string url)
    {
        using (StreamWriter sw = new StreamWriter("C:\temp.html"))
        {
            SimpleWorkerRequest worker = new SimpleWorkerRequest(url, null, sw);
            HttpRuntime.ProcessRequest(worker);
        }
                    // Ta-dah!  C:\temp.html has some html for you.
    }
}

Page对象上的ClientScript属性。

ASP的一个鲜为人知和很少使用的特性。网络:

标签的映射

它很少被使用，因为只有在特定的情况下你才会需要它，但当你需要它的时候，它是如此方便。

一些关于这个小功能的文章:

ASP中的标签映射。网 在ASP中使用标签映射。NET 2.0

从上一篇文章来看:

Tag mapping allows you to swap compatible controls at compile time on every page in your web application. A useful example is if you have a stock ASP.NET control, such as a DropDownList, and you want to replace it with a customized control that is derived from DropDownList. This could be a control that has been customized to provide more optimized caching of lookup data. Instead of editing every web form and replacing the built in DropDownLists with your custom version, you can have ASP.NET in effect do it for you by modifying web.config:

<pages>
 <tagMapping>
   <clear />
   <add tagType="System.Web.UI.WebControls.DropDownList"
        mappedTagType="SmartDropDown"/>
  </tagMapping>
</pages>
