gridview控件的使用，gridview控件选择功能

大家好，感谢邀请，今天来为大家分享一下gridview控件的使用的问题，以及和gridview控件选择功能的一些困惑，大家要是还不太明白的话，也没有关系，因为接下来将为大家分享，希望可以帮助到大家，解决大家的问题，下面就开始吧！

gridview控件的什么属性用来设置是否打开分页功能

当GridView中显示的记录很多的时候，可以通过GridView的分页功能来分页显示这些记录。

如果GridView是直接绑定数据库，则很简单：只要点击GridView空间左上角的小三角形，再弹出的选项中，将"启动分页"打上勾即可。如果是用代码实现，则需要这么做：

1、允许分页：设置AllowPaging=True；

2、设置GridView属性栏中PagerSetting里的一些属性中，定义分页的样式；

3、数据部署：将数据显示到GridView上；

4、加入相关事件：PageIndexChanged()、PageIndexChanging()；

5、如果要添加分页码显示，即显示当前在第几页，还需添加DataBound()事件。

怎样将LIST中的数据绑定到GridView，并实现增删改查

我的一个GridView操作文件,数据源是实体LIST,删改查功能都有了，你参考下 usingSystem; usingSystem.Collections; usingSystem.Collections.Generic; usingSystem.Configuration; usingSystem.Data; usingSystem.Linq; usingSystem.Web; usingSystem.Web.Security;
