Gridview中的Viewstate [英] Viewstate in Gridview

问题描述

我在Web应用程序中的gridview存在此问题:我在更新面板上具有此gridview，并且我想在用户单击搜索"页面时更新数据.按钮.用户完成搜索并在其中选择一条记录后 gridview，我想在我的代码中获取此选定记录并获取其内容.

I have this problem with a gridview in a webapplication: I have this gridview on an update panel and i want to update the data when the user clicks on a "search" button.  After the user has completed his search and selected a record in this gridview, i want to get this selected record in my code behind and get the contents.

问题是每次用户单击按钮时都会有一个回发.使用此回发，Gridview返回为空，我必须再次将其填充.

Problem though is that there is a postback each time the user clicks a button. With this postback the Gridview is returned empty and i have to fill it all over again. Is there a standard way to implement this?

推荐答案

请将按钮和gridview都放在更新面板中.

Please put both button and gridview in update panel.

否则，您必须为button_click编写触发器.

otherwise you have to write trigger for button_click.

要解决您的问题，最好在此处粘贴代码.

To resolve you problem, its better if you paste you code here.
