Question

我怀疑这很可能是由于错误形成的SQL，但我在ASP.NET Web窗体中连接到SQL数据源的GridView。当我单击“编辑命令”按钮时，它会更改为“编辑模板”。但是，当我单击“更新”按钮时，更改将写入所有行，而不仅仅是单击按钮的行。该页面有一个员工下拉列表，一旦选择了员工，GridView就会填充该员工当前的任务。

Answer 1

在更新中没有看到WHERE语句。

Answer 2

您的更新条款：

UpdateCommand="UPDATE [tblTaskTracker] SET  [TaskStatusID] = @TaskStatusID, 
[TaskPriorityID] = @TaskPriorityID, [DueDate] = @DueDate, [Notes] = @Notes, 
[CompDate] = @CompDate"

它没有WHERE过滤器。
