我翻遍了，研究了书籍，教程视频和大量文章，但我无法解决这个问题。在 Visual Studio 2010 中插入一个网格视图，我将数据源指定为访问数据库。在规范中，我包括插入、更新和删除记录的选项。网格视图出现在屏幕上，当我测试网页时，它会加载更新和插入等相关按钮。测试页面时，我单击更新按钮，更改一行，然后单击更新。页面恢复到以前的状态，记录保持不变。我刷新页面以确保它没有更新，它肯定没有。我完全按照教程进行操作，使用此方法时无法更新或删除字段。我使用的数据库是一个访问数据库，一个 mdb 文件。
我确定我在这里遗漏了一些非常简单的东西，但我不确定是什么。如果有人可以提供一些帮助，我将不胜感激！谢谢
这是我的表单代码。
