自动更新页面而不刷新页面 [英] auto update page without refreshing page

问题描述

您好，我有一个类似facebook的网页，并且当有新更新可用时，我没有要更新的内容，这意味着如果我在页面中具有下拉控件并从服务器上载新数据，则下拉列表将自动更新，而无需计时器控制，因为如果计时器将使用，则它将在页面上加载以供页面中的其他请求.(例如，facebook页面更新)

解决方案

这是不可能的.如果不刷新页面，则无法加载动态内容.您需要部分或全部刷新或重新加载页面.在这种情况下，您只能刷新页面中需要更新的那些区域.为此，您需要在此处使用更新面板.并每5分钟或根据您的要求刷新更新面板.

hello , i have web page like facebook and there no of content i want to update when new update are available ,means if i have dropdown control in page and upload new data from server then dropdown will automatically update without timer control,because if timer will use then it will take loading on page for other request in page..(Ex . facebook page update)

解决方案

It''s not possible. Without refreshing the page you cannot load the dynamic contents. You need to refresh or reload your page either partially or fully. In this case you can refresh only those area of the page which is required to be updated. For this, you need to use update panel there. And refresh the update panel in every 5 minutes or as per your requirements.
