我没有多次使用gridview数据控件。我有一个gridview，当用户点击编辑时，他们有文本框来填写（完成者，完成日期，用户创建，页数）。当他们单击“更新”时，我需要将数据插入到数据库中，并将更新的记录从gridview中隐藏（或删除）。我无法工作的唯一部分是更新数据库。
这是我的gridview代码：

GridLines="None" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowCancelingEdit="GridView1_RowCancelingEdit"

我没有收到任何错误 - 但数据库中的数据没有更新。提前致谢。

This C-sharpcorner article介绍如何使用SQL Server数据库和C＃中的ASP.NET 2.0 GridView控件查看，更新和删除数据。
祝你好运！答案 1 :(得分：0)
您尚未执行命令。你需要这样的东西：
sqlcon.ExecuteNonQuery();
您还需要为此创建连接。
答案 2 :(得分：0)
我运行了你的代码，并添加了一个快速的异常响应（你的'try catch'例程，你没有任何东西，当它捕获异常时显示回复给你，这就是为什么没有显示。）来检查什么异常呈现......就我而言，它出现的是......
发生与网络相关或特定于实例的错误 建立与SQL Server的连接。找不到服务器或 无法访问。验证实例名称是否正确 SQL Server配置为允许远程连接。 （提供者：命名 管道提供程序，错误：40 - 无法打开与SQL Server的连接）
我希望它，因为有防火墙不让我连接到你的服务器，为什么不运行它，让我们知道什么是异常
catch (Exception ex)
{
Response.Write(ex.Message);
}
