C# GridView更新问题
我很少使用gridview数据控件。我有一个gridview，当用户单击Edit时，他们会填写文本框（填写人、填写日期、用户创建、页数）。当他们单击“更新”时，我需要将数据插入数据库，并将更新后的记录从gridview中隐藏（或删除）。我唯一不能做的就是更新数据库 以下是我的gridview代码：C# GridView更新问题,c#,asp.net,sql,C#,Asp.net,Sql,我很少使用gridview数据控件。我有一个gridview，当用户单击Edit时，他们会填写文本框（填写人、填写日期、用户创建、页数）。当他们单击“更新”时，我需要将数据插入数据库，并将更新后的记录从gridview中隐藏（或删除）。我唯一不能做的就是更新数据库 以下是我的gridview代码： <asp:GridView ID="GridView1" runat="server" DataKeyNames="Job_No" AllowPaging="True" Au
