单击gridview外部的单个按钮，在gridview中保存多行 [英] save multiple row in gridview on click of single button outside of gridview

问题描述

大家好，

我正在用C#制作一个项目.在gridview中，我有两个三列ID，状态和注释.
对于状态，我在gridview列中使用了两个单选按钮.所以在我的gridview的每一行中，我在状态栏中有一个单选按钮，在注释栏中有一个文本框.
为保存更改，我在gridview之外使用了一个按钮.用于更新数据库中的更改.
我希望当用户单击保存hanges"按钮时，仅对注释或状态已更改的那些ID执行更新查询.意味着我不想为gridview的每一行执行更新查询.
所以我不明白我怎么会发现在哪个行中文本框的值被更改或未更改.

请给我任何想法.

在此先感谢

推荐答案

您可以添加一个隐藏字段
您可以在其中将从服务器接收的数据存储为字符串
按下按钮时
您可以比较网格视图和隐藏字段的数据
如果进行了任何更改，则保存其他明智的跳过...

in which you can store you data received from server as a string
when button press
you can compare data of grid view and hidden field
if any changed made then save other wise skip ...
