如何在没有更新面板的情况下完成回发后显示加载图像 [英] How Do I Display Loading Image Until The Postback Finishes Without Update Panel

问题描述

你好所有



我在回发时看到显示加载图像的示例数量。仅在回发开始时显示加载图像，直到回发结束。他们还使用了线程概念。并且加载图片只显示给定的线程时间。



但我的问题是：

如何在回发结束前显示加载图像没有更新面板。

请帮忙。



提前致谢。

推荐答案

使用ajax方法................. :)并做 xhr 请求

use ajax method.................:) and do a xhr request

检查在ASP.Net中的PostBack调用时显示加载图像 [ ^ ]

我用google搜索asp.net show image when when postback，这里有一些结果
