<p>Once the page is rendered to the client you have only two ways of forcing a refresh.
One is Javascript</p>

<pre><code>setTimeout("location.reload(true);", timeout);
</code></pre>

<p>The second is a Meta tag:</p>

<pre><code>&lt;meta http-equiv="refresh" content="600"&gt;
</code></pre>

<p>You can set the refresh intervals on the server side.</p>

<p>In my user controls, after updating data I do:</p>

<pre><code>  Response.Redirect(Request.RawUrl);    
</code></pre>

<p>That ensures that the page is reloaded, and it works fine from a user control.  You use RawURL and not <code>Request.Url.AbsoluteUri</code> to preserve any GET parameters that may be included in the request.</p>

<p>You probably don't want to use: <code>__doPostBack</code>, since many aspx pages behave differently when doing a postback.</p>

blocks|key|1275698|text|如果不想刷新整个页面，那么将想要刷新的内容包装在UpdatePanel中，然后执行异步回发如何？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1275699|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>If you don't want to do a full page refresh, then how about wrapping what you want to refresh inside of a UpdatePanel and then do an asynchronous postback?</p>


blocks|key|1275954|text|我个人需要确保页面保持状态，以便所有文本框和其他输入字段保持它们的值。通过执行元刷新，这就像是一个新的post，IsPostBack总是假的，所以你所有的控件都会再次处于初始化状态。要保留状态，请将此代码放在Page_Load()的末尾。在页面上创建一个与事件挂钩的隐藏按钮，类似于带有event+butRefresh_Click(...)的butRefresh。此代码在页面上设置一个计时器来触发回发，就像用户自己单击“刷新”按钮一样。保留所有状态和会话。享受吧！(附注:如果在回发时收到错误，您可能需要将该指令放入@Page+EnableEventValidation=中“false”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1275955|//tell+the+browser+to+post+back+again+in+5+seconds+while+keeping+state+of+all+controls

<p>I personally need to ensure the page keeps state, so all the text boxes and other input fields retain their values. by doing meta refresh it's like a new post, IsPostBack is always false so  all your controls are in the initialized state again. To retain state put this at the end of your Page_Load(). create a hidden button on the page with an event hooked up, something like butRefresh with event butRefresh_Click(...). This code sets a timer on the page to fire a postback just like a user clicked the refresh button themselves. all state and session is retained. Enjoy! (P.S. you may need to put the directive in the @Page header  EnableEventValidation="false" if you receive an error on postback.</p>

<pre><code>//tell the browser to post back again in 5 seconds while keeping state of all controls
ClientScript.RegisterClientScriptBlock(this.GetType(), "refresh", "&lt;script&gt;setTimeout(function(){ " + ClientScript.GetPostBackClientHyperlink(butRefresh, "refresh") + " },5000);&lt;/script&gt;");
</code></pre>


blocks|key|1275728|text|你不能这么做。如果您使用重定向(或任何其他服务器技术)，您将永远不会将实际页面发送到浏览器，而只会将页面重定向。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1275729|您必须使用meta标记或JavaScript来完成此操作，以便在页面显示一段时间后可以重新加载页面：|1275730|ScriptManager.RegisterStartupScript(this,+GetType(),+"refresh",+"window.setTimeout('window.location.reload(true);',5000);",+true);|code-block|syntax|javascript|1275731|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>You can't do that. If you use a redirect (or any other server technique) you will never send the actual page to the browser, only redirection pages.</p>

<p>You have to either use a meta tag or JavaScript to do this, so that you can reload the page after it has been displayed for a while:</p>

<pre><code>ScriptManager.RegisterStartupScript(this, GetType(), "refresh", "window.setTimeout('window.location.reload(true);',5000);", true);
