在更新面板中的gridview中使用下拉列表中选定的索引已更改事件 [英] Using dropdown Selected index changed event inside a gridview which is in update panel

问题描述

你好，



我在更新面板中有一个Gridview.在该Gridview中，我使用的是一个下拉列表，该列表具有选定的索引更改事件，并且第二个下拉列表取决于第一个dropdownlist值被填充.


但是我的整个页面都回发了.我不得不一次又一次地滚动整个gridview.

如何避免这种情况?

Hello,



I am having a gridview in an update Panel.Inside that Gridview I am using a dropdownlist which is having a selected index changed event and a second drop down gets filled depending upon the first dropdownlist value.


But My entire page is getting postback.I have to scroll the entire gridview again and again.

How to avoid this?



Bye

推荐答案

请确保已在.aspx文件中添加了ScriptManager.
您是否已将事件添加到UpdatePanel中的触发器?
我已经在这里简要回答过:已选中在更新面板中未触发变级事件 [ http://ajax.net-tutorials.com/controls/updatepanel-control/ [ ^ ]

祝你好运！

Do make sure that you have added ScriptManager in the .aspx file.
Have you added the events to Triggers in your UpdatePanel?
I have answered it briefly here :checked chaged event is not firing within update panel[^]
