加载程序图像在页面上呈现 [英] loader image on page rendering

问题描述

当我对gridview进行排序时，页面的所有内容都会重新加载.这样会给人留下不好的印象.
我只希望特定区域重新加载，并显示加载程序图像.

When i sort the gridview, all the contents of the page reload. So it create a bad impression.
I want that only the particular area reloads and it show a loader image.

推荐答案

在ASP.NET中使用UpdatePanel并向其中添加GridView .确保在.aspx文件中也添加了ScriptManager .然后使用UpdatePanel的触发器，其中将包含将重新加载Gridview的控件.

我已经在这里回答了:选中了事件不在更新面板中触发 [ http://www.asp.net/ajax/tutorials/understanding-asp-net-ajax-updatepanel-triggers [

Use an UpdatePanel in your ASP.NET and add a GridView into it. Make sure you have added ScriptManager in the .aspx file too. Then use the Triggers of the UpdatePanel which will contain the controls which will reload the Gridview.

I have answered it here : checked chaged event is not firing within update panel[^]
