处理从gridview模板字段触发事件时未显示的图像 [英] processing image not showing when event fired from gridview template field

问题描述

大家好，

我正在使用master-child page。在母版页中，我有scriptmanager，updatepanel和progress image。在一个子页面中，我有一个gridview和几个控件。 gridview还有2个下拉列表作为模板字段。

我的问题是：--- 每当触发页面控件（外部网格）事件时，进度图像在回发期间工作正常，但每当gridview模板字段控件的事件将触发未显示的进度图像。回发发生，我得到了想要的结果，但处理图像没有显示。



请帮帮我...

c）注册启动脚本，在启动脚本中，获取PageRequestManager.getInstance并添加initializeRquest和EndRequest。

d）在Initialize请求中查找图像将其style.display设置为阻止并在最终请求中将其style.display设置为无

Follow these steps :-
